Currently migration cleanup returns, after finishing, the number of documents removed - this information isn't sufficient to debug complex performance issues. More information (such as total data removed, avg document size, min/max, etc.) would be helpful for support to debug these issues and would be fairly simple to provide.
Recommend reporting this information periodically as well, as a way of determining status for long-running operations.
