Before you begin migrating, set up Migrate for Anthos and GKE by creating the processing cluster that you use to perform migrations, then install Migrate for Anthos and GKE on the cluster.
Choosing the type of processing cluster
The type of processing cluster depends on the source platform and type of application that you are migrating, as shown in the following table:
|Source platform||Application type||Processing cluster type|
|Compute Engine||Linux system||
||* Requires Migrate for Compute Engine version 4.11.|
If you are migrating a Linux or Windows workload currently deployed on Compute Engine, then as your processing cluster you use either a GKE or Anthos clusters on Google Cloud.
If you are migrating a Linux workload from VMware, you can use as your processing cluster Anthos clusters on VMware, or use GKE or Anthos clusters on Google Cloud. However, to use GKE or Anthos clusters on Google Cloud, you must also install Migrate for Compute Engine.
The choice of processing cluster for VMware or AWS can depend on several factors. For example, if you already have Anthos clusters on VMware or AWS available, you can use them for migrations.
Also, take into consideration the type of workload you are migrating. If you are migrating a stateless workload to a container, then you can easily use any of the supported processing clusters to perform the migration. Then, use the generated migration artifacts to deploy your workloads on the target environment.
If you are migrating a stateful workload, where data is extracted to a persistent volume, you might find it easier to create a processing cluster in the eventual deployment environment. That setup can simplify the migration of stateful workloads. See Setting the migration intent for more on stateless and stateful workloads.
Set up steps
Read the prerequisites for your migration environment.
Confirm that your workload's OS and source platform are compatible for migration by reviewing the prerequisites:
- Prerequisites for migrating Linux VMs using Google Cloud processing clusters
- Prerequisites for migrating Windows VMs using Google Cloud processing clusters
- Prerequisites for migrating Linux VMs using VMware processing clusters
- Prerequisites for migrating Linux VMs using AWS processing clusters (preview)
Enable the required Google services.
If you are using GKE or Anthos clusters on Google Cloud to migrate from VMware, AWS, or Azure, set up Migrate for Compute Engine.
Migrate for Compute Engine works with your source platform to facilitate the streaming of migration data from your source VMs.
Configure a processing cluster.
Set up a cluster for processing the migration:
Install Migrate for Anthos and GKE to your processing cluster.
