Plesk Migrator bug #PMT-4692 which will be fixed in upcoming product releases.
Until a fix became available, use the following steps as a workaround:

- Make sure that the service plan was created on the target Plesk server and modify the default server for MySQL is Service Plans > migrated-plan > Hosting Parameters.

- Remove the first migrated subscription fro, Subscriptions > example.com and migrate it again.
