The migration appears to be challenging due to operations being stored in a binary format. To accomplish this task, we would need to retrieve operations from DB, unmarshal them using the previous version of the protobuf message and then marshal them again with the new version before storing them back in DB.

To avoid the migration process, how about retaining the orders in the protobuf message as they are?

LGTM. 👍
