Once the input is prepared, you can easily migrate an entire TCA deployment topology.
You can use either of the following three approaches to perform migration operation:
Low Downtime Migration (Recommended)
Less User Intervention Migration
Granular Migration
All the CLIs take the same input format.
The migration operation is idempotent and re-entrant. If the migration operation fails, you can fix the error and retry the migration. If you cancel the migration, retry the migration operation by using the same CLI command.
The backup/migrate/deploy/revert/e2e-migrate operations are performed in the background. When you start the command, it starts a background process. You can monitor the status using status CLI. The migration tool prevents any of these operations to run in parallel. To start a new operation, wait till the current process to complete or cancel it using cancel CLI.
