Step-by-step migration

Once you have met the Migration prerequisites, configured your source MSR system and your target MSR system, and selected the storage mode, you can perform the migration workflow as a sequence of individual steps.

Migrations from MSR 2.9.x to 3.x.x must follow each of the five migration steps, whereas migrations from MSR 3.x.x source systems skip the verify, estimate, and transform steps, and instead begin with extract before proceeding directly to restore.

Important

All MMT commands that are run on MSR 3.x.x systems, including 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:

helm ls

• Verify the source system configuration
• Estimate the migration
• Extract the data
• Transform the data extract
• Restore the data extract
