Error VS403316 while using migration tool when migrating from ADO Server2022.0.1 to ADO Service

Yes, this error indicates inconsistencies in Team Foundation Version Control (TFVC) files within your collection:

• Missing file chunks in the TFVC database (tbl_content table stores files in 1MB chunks).
• Corrupted TFVC metadata due to prior database issues or incomplete repairs.
• SQL-level corruption—especially if DBCC CHECKDB was run with REPAIR_ALLOW_DATA_LOSS, which can remove chunks and trigger this error.

You may consider:

1. Restore from a clean backup:
• If you suspect corruption, restoring from a backup taken before any repair operations may help.
2. Identify and remove corrupted files:
• This is risky but technically, if restoring isn’t viable, you may need to locate the affected TFVC files and delete them manually
