Before you begin migrating, set up Migrate for Anthos and GKE by creating the processing cluster that you use to perform migrations, and then install Migrate for Anthos and GKE on the cluster.
Choose the type of processing cluster
The type of processing cluster depends on the source platform and the 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, you can use either a GKE cluster or an Anthos cluster on Google Cloud as your processing cluster.
If you are migrating a Linux workload from VMware, you can use an Anthos cluster on VMware, or you can use a GKE cluster or an Anthos cluster on Google Cloud as your processing cluster. However, to use a GKE cluster or an Anthos cluster on Google Cloud, you must also install Migrate for Compute Engine.
The choice of a processing cluster for VMware or AWS depends 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 that 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. You can 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.
For more information about stateless and stateful workloads, see Setting the migration intent.
Read the prerequisites for your migration environment.
The migration prerequisites are dependent on your specific migration environment. Confirm that your workloads' OS and source platform are compatible for migration by reviewing the prerequisites for your specific migration environment:
- 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)
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.
Set up a GKE or Anthos cluster for processing the migration. You do the migration by using this cluster before deploying to a production cluster. The GKE processing clusters can be located in the Cloud or on-premises:
Install and configure Migrate for Anthos and GKE on your processing cluster.
