We are migrating from SBS 2003 to SBS 2008. Our contractor is using a migration tool, and "middle-man" server to migrate everything.
We had nearly 60GB in our exchange DB, and the migration was at about the 32 hour mark when my boss called it off. (I think we would have been better to just bit the bullet and let it finish -- was probably only going to take another 5-10 hours)
Anyway -- we just archived 2/3 of the stuff out of the exchange DB. So we are now at 20GB. (though the physical files are 85GB, with 65GB logical free space)
Do we need to do an offline defrag before the next migration attempt, or should it just skip over all that logical whitespace?
