I rencently used the SQL Server Migration Assistant to import a database into SQL Server 2005. I observed that numerous tables which were imported happen to be ammended with a brand new column known as SSMA_timestamp.

Can anybody let me know what to and just how it might be used?

I believe this really is produced to ensure that the Migration assistant can identify changes towards the data throughout the migration. I do not believe it is used after migration is done, so it ought to be safe to decrease these new posts when you are sure things are done.
