Perform Migration

To migrate images, repositories, and tags from an MSR 2.9 or MSR 3.1 environment to MSR 4.x, you can either run the migration as a single comprehensive operation, which is the recommended path, or break it into specific steps if needed. The migration tool supports both full and partial migrations, with detailed options described in the --help flag and active configuration in the --config flag.

To migrate all data in one step, run:

docker run --rm \
  -v ./sql:/app/data/sql \
  -v ./csv:/app/data/csv \
  -v ./config:/app/config \
  --network host \
  registry.mirantis.com/msrh/migrate:latest poetry run migration --all

To perform the migration in individual steps:

• Migrate Projects

• Migrate Permissions

• Migrate Push and Poll Mirroring Policies

To view all available options for partial migrations use the --help flag with the migration tool.
