Post PST Migration Tasks

[Ray_Hasham]

I am migrating a large number of PSTs using the server driven migration. I just realised that the original PST is empty once the migration is succesful. Is there a way to leave the original PST intact? This will assist us if we have to go back to check any particular items that the users doubt were not migrated?

 ... I don't think you can do that.  What you should do is keep the migration reports, that shows the PST file contents, the number of items archived, and the number of items moved to the mailbox (which will include any ineligible items).  It shows other parts of your policy also, which is good for reference.

I think the only way of "going back" would be to grab the PST from a backup.

Thank you Rob. That makes sense.
