Thank you for the insight, I'll have to take a close look and break this plan down a little bit. As of now the largest few databases are around 50GB each but there are only 3 to 4 of those out of around 60 DBs. Overall the plan could use a good revamping so that's something I need to work on in the coming days.

As for the precedence constraints, am I missing something? I feel like I understand it, but it just doesn't seem to work for me.
