Post-Migration Cleanup

Caution

Before deprecating MSR 2.9 or MSR 3.1, run the migration one last time to ensure all data has been transferred.

When you no longer plan to push data to your MSR 2.9 or MSR 3.1 instances, you can remove the replication schedules:

1. Remove the trigger of replication rules:

   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 --remove-replication-rules-trigger
   

2. Check your Replications service dashboard to verify if they were switched to manual.

3. Delete all replication rules created for the migration, use the --delete-migration-rules option. This removes all rules prefixed with migration-rule-.

   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 --delete-migration-rules
   

Additional considerations

Re-running the script with --trigger-replication-rules re-enables scheduled execution for all migration-rule replication rules. The schedule is defined by the REPLICATION_TRIGGER_CRON environment variable.

Use the appropriate command-line flags based on the replication policy type:

• --trigger-push-replication-rules and --remove-push-replication-rules-trigger for push policies

• --trigger-pull-replication-rules and --remove-pull-replication-rules-trigger for pull policies

Before performing any deprecating operations, use --export-all-replication-rules to back up all replication rules from the replication_policy table in MSR 4.

Delete Custom Replication Rules

You can delete all pull or push replication rules or filter them by the source or destination registry domains.

• To delete all pull replication rules:

  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 --delete-pull-replication-rules
  

• To delete pull replication rules that match a specific source registry domain, for example index.docker.io:

  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 --delete-pull-replication-rules --replication-rule-remote-registry index.docker.io
  

• To delete all push replication rules:

  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 --delete-push-replication-rules
  

• To delete push replication rules that match a specific source registry domain, for example index.docker.io:

  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 --delete-push-replication-rules --replication-rule-remote-registry index.docker.io
