With the upcoming end-of-life (EOL) of MSR 3.1.x, Mirantis encourages you to upgrade to the latest supported version to ensure continued support and security updates.

Simplified migration

Available since MMT 2.0.3

The migrate command introduced in MMT 2.0.3 streamlines the legacy multi-step migration by reducing verification, estimation, data extraction, transformation, and restoration into one or two steps.

Before you can perform the migration, it is necessary to:

• Meet all Migration prerequisites.

• Configure your source MSR system and your target MSR system.

• Select the storage mode.

Important

All MMT commands run on MSR 3.x.x systems, both source and target deployments, must include the --fullname option, which specifies the name of the MSR instance.

To obtain the name of your MSR instance:

• MSR Operator-managed deployments:

  kubectl get msrs.msr.mirantis.com
  

• Helm-managed deployments:

  helm ls
  

• Swarm migration
• Kubernetes migration
