Hi,
Never "Repair Project" directly, Please have a back up & Perform the same.
I Guesst, this process may not Fix the Issue.
Please check thesize attach folder in the repositories of the both versions (From & to Migrated versions).
If it is happening, remove the project and restore the same in the same location, check for the Repository migration status to complete for 100%.
Let me know if you still facing the issue.
Thanks
Damodar Reddy
