I'm in the process of performing a side by side migration from 2007 R2 to 2012 R2. I'm at the step where I'm exporting all of my unsealed MP's from 2007 and importing them into 2012 R2. My concern is that I have not yet multi-homed all of my agents yet, so I was wondering if importing an MP w/ overrides for an agent that 2012 R2 does not know about may confuse things.
My question is, do I need to multi-home the agents before importing the unsealed MP's?
