Upgrading Apigee hybrid to version 1.11

This procedure covers upgrading from Apigee hybrid version 1.10.x to Apigee hybrid version 1.11.2 and from previous releases of hybrid 1.11.x to version 1.11.2.

Use the same procedures for minor version upgrades (for example version 1.10 to 1.11) and for patch release upgrades (for example 1.11.0 to 1.11.2).

If you are upgrading from Apigee hybrid version 1.9 or older, you must first upgrade to hybrid version 1.10 before upgrading to version 1.11.2. See the instructions for Upgrading Apigee hybrid to version 1.10.

Upgrading to version 1.11.2 overview

Upgrading to Apigee hybrid version 1.11 may require downtime.

When upgrading the Apigee controller to version 1.11.2, all Apigee deployments undergo a rolling restart. To minimize downtime in production hybrid environments during a rolling restart, make sure you are running at least two clusters (in the same or different region/data center). Divert all production traffic to a single cluster and take the cluster you are about to upgrade offline, and then proceed with the upgrade process. Repeat the process for each cluster.

Apigee recommends upgrading all clusters as soon as possible to reduce the chances of production impact. There is no time limit on when all remaining clusters must be upgraded after the first one is upgraded. However, until all remaining clusters are upgraded the following operations will be impacted:

Cassandra backup and restore cannot work with mixed versions. For example, a backup from Hybrid 1.10 cannot be used to restore a Hybrid 1.11 instance.
Cassandra data streaming will not work between mixed Hybrid versions. Therefore, your Cassandra clusters cannot scale horizontally.
Region expansion and decommissioning will be impacted, because these operations depend on Cassandra data streaming.

The procedures for upgrading Apigee hybrid are organized in the following sections:

Prepare to upgrade.
Install hybrid runtime version 1.11.2.

Prerequisites

These upgrade instructions assume you have Apigee hybrid version 1.10.x installed and wish to upgrade it to version 1.11.2. If you are updating from an earlier version, see the instructions for Upgrading Apigee hybrid to version 1.10.

Helm charts and `apigeectl`

In version 1.11 you can choose to install and manage Apigee hybrid with either Helm charts or apigeectl. Apigee recommends using Helm to manage your installation.

Migrating to v1.11 with Helm from v1.10 with `apigeectl`

To upgrade to Apigee hybrid v1.11 managed by Helm from a hybrid v1.10 installation managed with apigeectl:

First, migrate your v1.10 installation Helm by following the instructions in Migrate Apigee hybrid to Helm charts from apigeectl.
Follow the instructions for Helm charts below to upgrade your installation.
Note: When upgrading a migrated installation, you will need to insert a --force flag in the helm upgrade commands.

Prepare to upgrade to version 1.11

Note: When migrating from Apigee hybrid v1.10 to v1.11, after transitioning from apigeectl to Helm charts in the previous step, you must follow the instructions under the helm tab. After transitioning to Helm you must continue with Helm in further upgrades.

Back up your hybrid installation (recommended)

Helm

These instructions use the environment variable APIGEE_HELM_CHARTS_HOME for the directory in your file system where you have installed the Helm charts. If needed, change directory into this directory and define the variable with the following command:
Linux
```
export APIGEE_HELM_CHARTS_HOME=$PWD
echo $APIGEE_HELM_CHARTS_HOME
```
Mac OS
```
export APIGEE_HELM_CHARTS_HOME=$PWD
echo $APIGEE_HELM_CHARTS_HOME
```
Windows
```
set APIGEE_HELM_CHARTS_HOME=%CD%
echo %APIGEE_HELM_CHARTS_HOME%
```
Make a backup copy of your version 1.10 $APIGEE_HELM_CHARTS_HOME/ directory. You can use any backup process. For example, you can create a tar file of your entire directory with:
```
tar -czvf $APIGEE_HELM_CHARTS_HOME/../apigee-helm-charts-v1.10-backup.tar.gz $APIGEE_HELM_CHARTS_HOME
```
Back up your Cassandra database following the instructions in Cassandra backup and recovery.

If you are using service cert files (.json) in your overrides to authenticate service accounts, make sure your service account cert files reside in the correct Helm chart directory. Helm charts cannot read files outside of each chart directory.

This step is not needed if you are using Kubernetes secrets or Workload Identity to authenticate service accounts.

The following table shows the destination for each service account file, depending on your type of installation:

Prod

Service account	Default filename	Helm chart directory
`apigee-cassandra`	`PROJECT_ID-apigee-cassandra.json`	`$APIGEE_HELM_CHARTS_HOME/apigee-datastore/`
`apigee-logger`	`PROJECT_ID-apigee-logger.json`	`$APIGEE_HELM_CHARTS_HOME/apigee-telemetry/`
`apigee-mart`	`PROJECT_ID-apigee-mart.json`	`$APIGEE_HELM_CHARTS_HOME/apigee-org/`
`apigee-metrics`	`PROJECT_ID-apigee-metrics.json`	`$APIGEE_HELM_CHARTS_HOME/apigee-telemetry/`
`apigee-runtime`	`PROJECT_ID-apigee-runtime.json`	`$APIGEE_HELM_CHARTS_HOME/apigee-env`
`apigee-synchronizer`	`PROJECT_ID-apigee-synchronizer.json`	`$APIGEE_HELM_CHARTS_HOME/apigee-env/`
`apigee-udca`	`PROJECT_ID-apigee-udca.json`	`$APIGEE_HELM_CHARTS_HOME/apigee-org/`
`apigee-watcher`	`PROJECT_ID-apigee-watcher.json`	`$APIGEE_HELM_CHARTS_HOME/apigee-org/`

Non-prod

Make a copy of the apigee-non-prod service account file in each of the following directories:

Service account	Default filename	Helm chart directories
`apigee-non-prod`	`PROJECT_ID-apigee-non-prod.json`	`$APIGEE_HELM_CHARTS_HOME/apigee-datastore/` `$APIGEE_HELM_CHARTS_HOME/apigee-telemetry/` `$APIGEE_HELM_CHARTS_HOME/apigee-org/` `$APIGEE_HELM_CHARTS_HOME/apigee-env/`

Make sure that your TLS certificate and key files (.crt, .key, and/or .pem) reside in the $APIGEE_HELM_CHARTS_HOME/apigee-virtualhost/ directory.

`apigeectl`

The examples in these instructions use the following directory structure. Your installation may be different. Adjust the instructions to the structure of your installation.

hybrid-v1.11-root-directory/
└── apigeectl/
    └── config/
    └── plugins/
    └── templates/
    └── tools/
└── hybrid-files/
    └── overrides/
    └── service-accounts/
    └── certs/
hybrid-v1.10-root-directory/

These instructions use the environment variable APIGEECTL_HOME for the directory in your file system where you have installed apigeectl. If needed, change directory into your apigeectl directory and define the variable with the following command:
Linux
```
export APIGEECTL_HOME=$PWD
echo $APIGEECTL_HOME
```
Mac OS
```
export APIGEECTL_HOME=$PWD
echo $APIGEECTL_HOME
```
Windows
```
set APIGEECTL_HOME=%CD%
echo %APIGEECTL_HOME%
```
Make a backup copy of your version 1.10 $APIGEECTL_HOME/ directory. For example:
```
tar -czvf $APIGEECTL_HOME/../apigeectl-v1.10-backup.tar.gz $APIGEECTL_HOME
```
Back up your Cassandra database following the instructions in Cassandra backup and recovery.

Upgrade your Kubernetes version

About attached clusters

For Apigee hybrid versions 1.7.x and older, you must use GKE attached clusters if you want to run Apigee hybrid in a multi-cloud context on Elastic Kubernetes Service (EKS), Azure Kubernetes Service (AKS), or another supported third-party Kubernetes service provider. Cluster attachment allows Google to measure the usage of Anthos Service Mesh.

For Apigee hybrid version 1.8.x, GKE attached clusters are required if you are using Anthos Service Mesh for your ingress gateway. If you are using Apigee ingress gateway, attached clusters are optional.

Install the hybrid 1.11.2 runtime

Helm

Prepare for the Helm charts upgrade

Make the following change to your overrides.yaml file to enable the apigee-operator and apigee-env charts ot use the correct tag, 1.11.2-hotfix.2:

ao:
  image:
    url: "gcr.io/apigee-release/hybrid/apigee-operators"
    tag: "1.11.2-hotfix.2"
runtime:
  image:
    url: "gcr.io/apigee-release/hybrid/apigee-runtime"
    tag: "1.11.2-hotfix.2"

See Apigee 1.11.2-hotfix.2 release notes.

Pull the Apigee Helm charts.

Apigee hybrid charts are hosted in Google Artifact Registry:

oci://us-docker.pkg.dev/apigee-release/apigee-hybrid-helm-charts

Using the pull command, copy all of the Apigee hybrid Helm charts to your local storage with the following command:

export CHART_REPO=oci://us-docker.pkg.dev/apigee-release/apigee-hybrid-helm-charts
export CHART_VERSION=1.11.2
helm pull $CHART_REPO/apigee-operator --version $CHART_VERSION --untar
helm pull $CHART_REPO/apigee-datastore --version $CHART_VERSION --untar
helm pull $CHART_REPO/apigee-env --version $CHART_VERSION --untar
helm pull $CHART_REPO/apigee-ingress-manager --version $CHART_VERSION --untar
helm pull $CHART_REPO/apigee-org --version $CHART_VERSION --untar
helm pull $CHART_REPO/apigee-redis --version $CHART_VERSION --untar
helm pull $CHART_REPO/apigee-telemetry --version $CHART_VERSION --untar
helm pull $CHART_REPO/apigee-virtualhost --version $CHART_VERSION --untar

Install cert-manager if needed.
If you need to upgrade your cert-manager version, install the new version with the following command:
```
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.11.1/cert-manager.yaml
```

Install the updated Apigee CRDs:

Note: This is the only supported method for installing Apigee CRDs. Do not use kubectl apply without -k, do not omit --server-side.

Use the kubectl dry-run feature by running the following command:

kubectl apply -k  apigee-operator/etc/crds/default/ --server-side --force-conflicts --validate=false --dry-run=server

After validating with the dry-run command, run the following command:

kubectl apply -k  apigee-operator/etc/crds/default/ --server-side --force-conflicts --validate=false

Validate the installation with the kubectl get crds command:

kubectl get crds | grep apigee

Your output should look something like the following:

Check the labels on the cluster nodes. By default, Apigee schedules data pods on nodes with the label cloud.google.com/gke-nodepool=apigee-data and runtime pods are scheduled on nodes with the label cloud.google.com/gke-nodepool=apigee-runtime. You can customize your node pool labels in the overrides.yaml file.

For more information, see Configuring dedicated node pools.

Install the Apigee hybrid Helm charts

Note: Before executing any of the Helm upgrade/install commands, use the Helm dry-run feature by adding --dry-run at the end of the command. See helm -h to list supported commands, options, and usage.

If you have not, navigate into your APIGEE_HELM_CHARTS_HOME directory. Run the following commands from that directory.

apigee-org1-dev-xxx            running     2d

Upgrade the environment groups (virtualhosts).
1. You must upgrade one environment group (virtualhost) at a time. Specify the environment group with --set envgroup=ENV_GROUP_NAME. Repeat the following commands for each env group mentioned in the overrides.yaml file:
  Dry run:
```
helm upgrade ENV_GROUP_RELEASE_NAME apigee-virtualhost/ \
  --install \
  --namespace apigee \
  --set envgroup=ENV_GROUP_NAME \
  -f OVERRIDES_FILE \
  --dry-run
```
  ENV_GROUP_RELEASE_NAME is the name with which you previously installed the apigee-virtualhost chart. In hybrid v1.10, it is usually apigee-virtualhost-ENV_GROUP_NAME. In Hybrid v1.11 and newer it is usually ENV_GROUP_NAME.
  
  Upgrade the chart:
```
helm upgrade ENV_GROUP_RELEASE_NAME apigee-virtualhost/ \
  --install \
  --namespace apigee \
  --set envgroup=ENV_GROUP_NAME \
  -f OVERRIDES_FILE
```
  Note: For migrated installations, use:
```
helm upgrade ENV_GROUP_RELEASE_NAME apigee-virtualhost/ \
  --install \
  --namespace apigee \
  --set envgroup=ENV_GROUP_NAME \
  --force \
  -f OVERRIDES_FILE
```
  Note: ENV_GROUP_RELEASE_NAME must be unique within the apigee namespace.
  For example, if you have a an environment named prod and an environment group named prod, set the value of ENV_GROUP_RELEASE_NAME to something unique, like prod-envgroup.
2. Check the state of the ApigeeRoute (AR).
  Installing the virtualhosts creates ApigeeRouteConfig (ARC) which internally creates ApigeeRoute (AR) once the Apigee watcher pulls env group related details from the control plane. Therefore, check that the corresponding AR's state is running:
```
kubectl -n apigee get arc
```
```
NAME                                STATE   AGE
apigee-org1-dev-egroup                       2d
```
```
kubectl -n apigee get ar
```
```
NAME                                        STATE     AGE
apigee-org1-dev-egroup-xxxxxx                running   2d
```

`apigeectl`

Store the latest version number in a variable using the following command:

Linux

export VERSION=$(curl -s \
  https://storage.googleapis.com/apigee-release/hybrid/apigee-hybrid-setup/current-version.txt?ignoreCache=1)

Mac OS

export VERSION=$(curl -s \
  https://storage.googleapis.com/apigee-release/hybrid/apigee-hybrid-setup/current-version.txt)

Windows

for /f "tokens=*" %a in ('curl -s ^
  https://storage.googleapis.com/apigee-release/hybrid/apigee-hybrid-setup/current-version.txt') ^
do set VERSION=%a

Check that the variable was populated with a version number using the following command. If you want to use a different version, you can save that in an environment variable instead.
```
echo $VERSION
```
You should see the latest Apigee hybrid version:
```
  1.11.2
```
Be sure you are in the hybrid base directory (the parent of the directory where the apigeectl executable file is located):
```
cd $APIGEECTL_HOME/..
```

Download the release package for your operating system using the following command. Be sure to select your platform in the following table:

Linux

Linux 64 bit:

curl -LO \
  https://storage.googleapis.com/apigee-release/hybrid/apigee-hybrid-setup/$VERSION/apigeectl_linux_64.tar.gz

Mac OS

Mac 64 bit:

curl -LO \
  https://storage.googleapis.com/apigee-release/hybrid/apigee-hybrid-setup/$VERSION/apigeectl_mac_64.tar.gz

Windows

Windows 64 bit:

curl -LO ^
  https://storage.googleapis.com/apigee-release/hybrid/apigee-hybrid-setup/%VERSION%/apigeectl_windows_64.zip

Rename your current apigeectl/ directory to a backup directory name. For example:

Linux

mv $APIGEECTL_HOME/ $APIGEECTL_HOME-v1.10/

Mac OS

mv $APIGEECTL_HOME/ $APIGEECTL_HOME-v1.10/

Windows

rename %APIGEECTL_HOME% %APIGEECTL_HOME%-v1.10

Extract the downloaded gzip file contents into your hybrid base directory. The hybrid base directory is the directory where the renamed apigeectl-v1.10 directory is located:
Linux
```
tar xvzf filename.tar.gz -C ./
```
Mac OS
```
tar xvzf filename.tar.gz -C ./
```
Windows
```
tar xvzf filename.zip -C ./
```
The tar contents are, by default, expanded into a directory with the version and platform in its name. For example: ./apigeectl_1.11.2-xxxxxxx_linux_64. Rename that directory to apigeectl using the following command:
Linux
```
mv apigeectl_1.11.2-xxxxxxx_linux_64 apigeectl
```
Mac OS
```
mv apigeectl_1.11.2-xxxxxxx_mac_64 apigeectl
```
Windows
```
rename apigeectl_1.11.2-xxxxxxx_windows_64 apigeectl
```
Change to the apigeectl directory:
```
cd ./apigeectl
```
This directory is the apigeectl home directory. It is where the apigeectl executable command is located.
These instructions use the environment variable $APIGEECTL_HOME for the directory in your file system where the apigeectl utility is installed. If needed, change directory into your apigeectl directory and define the variable with the following command:
Linux
```
export APIGEECTL_HOME=$PWD
```
```
echo $APIGEECTL_HOME
```
Mac OS
```
export APIGEECTL_HOME=$PWD
```
```
echo $APIGEECTL_HOME
```
Windows
```
set APIGEECTL_HOME=%CD%
```
```
echo %APIGEECTL_HOME%
```
Verify the version of apigeectl with the version command:
```
./apigeectl version
```
```
Version: 1.11.2
```
Create a hybrid-base-directory/hybrid-files directory, and then move into it. The hybrid-filesdirectory is where configuration files such as the overrides file, certs, and service accounts are located. For example:
Linux
```
mkdir $APIGEECTL_HOME/../hybrid-files
```
```
cd $APIGEECTL_HOME/../hybrid-files
```
Mac OS
```
mkdir $APIGEECTL_HOME/../hybrid-files
```
```
cd $APIGEECTL_HOME/../hybrid-files
```
Windows
```
mkdir %APIGEECTL_HOME%/../hybrid-files
```
```
cd %APIGEECTL_HOME%/../hybrid-files
```
Verify that kubectl is set to the correct context using the following command. The current context should be set to the cluster in which you are upgrading Apigee hybrid.
```
kubectl config get-contexts | grep \*
```
In the hybrid-files directory:
1. Update the following symbolic links to $APIGEECTL_HOME. These links allow you to run the newly installed apigeectl command from inside the hybrid-files directory:
```
ln -nfs $APIGEECTL_HOME/tools tools
ln -nfs $APIGEECTL_HOME/config config
ln -nfs $APIGEECTL_HOME/templates templates
ln -nfs $APIGEECTL_HOME/plugins plugins
```
2. To check that the symlinks were created correctly, execute the following command and make sure the link paths point to the correct locations:
```
ls -l | grep ^l
```

Make the following change to your overrides.yaml file to enable the Operator and Runtime to use the correct tag, 1.11.2-hotfix.2:

ao:
  image:
    url: "gcr.io/apigee-release/hybrid/apigee-operators"
    tag: "1.11.2-hotfix.2"
runtime:
  image:
    url: "gcr.io/apigee-release/hybrid/apigee-runtime"
    tag: "1.11.2-hotfix.2"

See Apigee 1.11.2-hotfix.2 release notes.

Do a dry run initialization to check for errors:
```
${APIGEECTL_HOME}/apigeectl init -f OVERRIDES_FILE --dry-run=client
```
Where OVERRIDES_FILE is the name of your overrides file, for example ./overrides/overrides.yaml.

Tip: You can replace OVERRIDES_FILE in the code sample above with the name and path to your overrides file, and every instance on this page will be replaced.
If there are no errors, initialize hybrid 1.11.2:
```
$APIGEECTL_HOME/apigeectl init -f OVERRIDES_FILE
```
Note: apigeectl installs and configures Apigee ingress gateway when you run apigeectl init.
Check the initialization status:
```
$APIGEECTL_HOME/apigeectl check-ready -f OVERRIDES_FILE
```
On success, the output says: All containers ready.
```
kubectl describe apigeeds -n apigee
```
In the output, look for State: running.
Check for errors with a dry run of the apply command using the --dry-run flag:
```
$APIGEECTL_HOME/apigeectl apply -f OVERRIDES_FILE --dry-run=client
```
If there are no errors, apply your overrides. Select and follow the instructions for production environments or non-prod environments, depending on your installation.
Production

For production environments, upgrade each hybrid component individually, and check the status of the upgraded component before proceeding to the next component.
1. Be sure you are in the hybrid-files directory.
2. Apply your overrides to upgrade Cassandra:
  $APIGEECTL_HOME/apigeectl apply -f OVERRIDES_FILE --datastore
3. Check completion:
  $APIGEECTL_HOME/apigeectl check-ready -f OVERRIDES_FILE
  Tip: If check-ready fails, you can get more information about your pods with:
  kubectl -n NAMESPACE get pods
  
  Where NAMESPACE is your Apigee hybrid namespace.
  Proceed to the next step only when the pods are ready.
4. Apply your overrides to upgrade Telemetry components and check completion:
  $APIGEECTL_HOME/apigeectl apply -f OVERRIDES_FILE --telemetry
  $APIGEECTL_HOME/apigeectl check-ready -f OVERRIDES_FILE
5. Bring up Redis components:
  $APIGEECTL_HOME/apigeectl apply -f OVERRIDES_FILE --redis
6. Apply your overrides to upgrade the org-level components (MART, Watcher and Apigee Connect) and check completion:
  $APIGEECTL_HOME/apigeectl apply -f OVERRIDES_FILE --org
  $APIGEECTL_HOME/apigeectl check-ready -f OVERRIDES_FILE
7. Apply your overrides to upgrade your environments. You have two choices:
  - Environment by environment: Apply your overrides to one environment at a time and check completion. Repeat this step for each environment:
    $APIGEECTL_HOME/apigeectl apply -f OVERRIDES_FILE --env ENV_NAME
    
    $APIGEECTL_HOME/apigeectl check-ready -f OVERRIDES_FILE
    
    Where ENV_NAME is the name of the environment you are upgrading.
  - All environments at one time: Apply your overrides to all environments at once and check completion:
    $APIGEECTL_HOME/apigeectl apply -f OVERRIDES_FILE --all-envs
    
    $APIGEECTL_HOME/apigeectl check-ready -f OVERRIDES_FILE
8. Apply your overrides to upgrade the virtualhosts components and check completion:
  $APIGEECTL_HOME/apigeectl apply -f OVERRIDES_FILE --settings virtualhosts
  $APIGEECTL_HOME/apigeectl check-ready -f OVERRIDES_FILE
Non-prod

In most non-production, demo, or experimental environments, you can apply the overrides to all components at once. If your non-production environment is large and complex or closely mimics a production environment, you may want to use the instructions for upgrading production environments.
1. Be sure you are in the hybrid-files directory.
2. $APIGEECTL_HOME/apigeectl apply -f OVERRIDES_FILE
3. Check the status:
  $APIGEECTL_HOME/apigeectl check-ready -f OVERRIDES_FILE

Rolling back an upgrade

Follow these steps to roll back a previous upgrade:

Helm

To rollback to the previous version, use the charts charts and the overrides file from the previous installation.

Create the following environment variable:
- PREVIOUS_HELM_CHARTS_HOME: The directory where the previous Apigee hybrid Helm charts are installed. This is the version you are rolling back to.
Roll back the virtualhosts. Repeat the following command for each environment group mentioned in the overrides file.
```
helm upgrade ENV_GROUP_RELEASE_NAME $PREVIOUS_HELM_CHARTS_HOME/apigee-virtualhost/ \
  --namespace apigee \
  --atomic \
  --set envgroup=ENV_GROUP_NAME \
  -f PREVIOUS_OVERRIDES_FILE
```
ENV_GROUP_RELEASE_NAME is the name with which you previously installed the apigee-virtualhost chart. In hybrid v1.10, it is usually apigee-virtualhost-ENV_GROUP_NAME. In Hybrid v1.11 and newer it is usually ENV_GROUP_NAME.
Roll back Envs. Repeat the following command for each environment mentioned in the overrides file.
```
helm upgrade apigee-env-ENV_NAME $PREVIOUS_HELM_CHARTS_HOME/apigee-env/ \
  --install \
  --namespace apigee \
  --atomic \
  --set env=ENV_NAME \
  -f PREVIOUS_OVERRIDES_FILE
```
ENV_RELEASE_NAME is the name with which you previously installed the apigee-env chart. In hybrid v1.10, it is usually apigee-env-ENV_NAME. In Hybrid v1.11 and newer it is usually ENV_NAME.

Roll back Org:

helm upgrade ORG_NAME $PREVIOUS_HELM_CHARTS_HOME/apigee-org/ \
  --install \
  --namespace apigee \
  --atomic \
  -f PREVIOUS_OVERRIDES_FILE

Roll back the Ingress Manager:

helm upgrade ingress-manager $PREVIOUS_HELM_CHARTS_HOME/apigee-ingress-manager/ \
  --install \
  --namespace apigee \
  --atomic \
  -f PREVIOUS_OVERRIDES_FILE

Roll back Redis:

helm upgrade redis $PREVIOUS_HELM_CHARTS_HOME/apigee-redis/ \
  --install \
  --namespace apigee \
  --atomic \
  -f PREVIOUS_OVERRIDES_FILE

Roll back Apigee Telemetry:

helm upgrade telemetry $PREVIOUS_HELM_CHARTS_HOME/apigee-telemetry/ \
  --install \
  --namespace apigee \
  --atomic \
  -f PREVIOUS_OVERRIDES_FILE

Roll back Apigee Datastore (the Cassandra database component):

helm upgrade datastore $PREVIOUS_HELM_CHARTS_HOME/apigee-datastore/ \
  --install \
  --namespace apigee \
  --atomic \
  -f PREVIOUS_OVERRIDES_FILE

Roll back the Apigee Controller:

helm upgrade operator $PREVIOUS_HELM_CHARTS_HOME/apigee-operator/ \
  --install \
  --namespace apigee-system \
  --atomic \
  -f PREVIOUS_OVERRIDES_FILE

Roll back the Apigee hybrid CRDs:

  kubectl apply -k  $PREVIOUS_HELM_CHARTS_HOME/apigee-operator/etc/crds/default/ --server-side --force-conflicts --validate=false

`apigeectl`

Clean up completed jobs for the hybrid runtime namespace, where NAMESPACE is the namespace specified in your overrides file, if you specified a namespace. If not, the default namespace is apigee:
```
kubectl delete job -n NAMESPACE \
  $(kubectl get job -n NAMESPACE \
  -o=jsonpath='{.items[?(@.status.succeeded==1)].metadata.name}')
```

Clean up completed jobs for the apigee-system namespace:

kubectl delete job -n apigee-system \
  $(kubectl get job -n apigee-system \
  -o=jsonpath='{.items[?(@.status.succeeded==1)].metadata.name}')

Change the APIGEECTL_HOME variable to point to the directory that contains the previous version of apigeectl. For example:
```
export APIGEECTL_HOME=PATH_TO_PREVIOUS_APIGEECTL_DIRECTORY
```

Run the following commands in the root directory of the installation you want to roll back to. Be sure to use the original overrides file for the version you wish to roll back to:

In the hybrid-files directory, run apigeectl apply:
```
$APIGEECTL_HOME/apigeectl apply -f ORIGINAL_OVERRIDES_FILE
```
Where ORIGINAL_OVERRIDES_FILE is the relative path and filename of the overrides file for your previous version hybrid installation, for example, ./overrides/overrides1.10.yaml.
Check the status of your pods:
```
kubectl -n NAMESPACE get pods
```
Where NAMESPACE is your Apigee hybrid namespace.

Check the status of apigeeds:

kubectl describe apigeeds -n apigee

Your output should look something like:

Status:
  Cassandra Data Replication:
  Cassandra Pod Ips:
    10.8.2.204
  Cassandra Ready Replicas:  1
  Components:
    Cassandra:
      Last Successfully Released Version:
        Revision:  v1-f8aa9a82b9f69613
        Version:   v1
      Replicas:
        Available:  1
        Ready:      1
        Total:      1
        Updated:    1
      State:        running
  Scaling:
    In Progress:         false
    Operation:
    Requested Replicas:  0
  State:                 running

Proceed to the next step only when the apigeeds pod is running.

Run the following command to make note of what your new replica count values will be for the message processor after the upgrade. If these values do not match what you have set previously, change the values in your overrides file to match your previous configuration.
```
apigeectl apply -f ORIGINAL_OVERRIDES_FILE --dry-run=client --print-yaml --env ENV_NAME 2>/dev/null |grep "runtime:" -A 25 -B 1| grep "autoScaler" -A 2
```
Your output should look something like:
```
      autoScaler:
        minReplicas: 2
        maxReplicas: 10
```

Run apigeectl init:

$APIGEECTL_HOME/apigeectl init -f ORIGINAL_OVERRIDES_FILE
