Using Quest to migrate mailboxes between Exchange orgs
Posted on 2010-08-31
We are soon going to start work on the following project and I was hoping someone could provide me with some background info help us kick off :)
Basically, we are running Exchange 2003/AD 2003 and are migrating to Exchange 2010/ AD 2008. We have created a new AD forest running 2008 DC's with 2010 Exchange servers.
Now I am looking at how we're going to move the mailboxes from 2003 to 2010. AFAIK, Exchange does not support mailbox moves between different orgs. I understand Quest has tools that can carry this out well.
Question1: When Quest 'moves' the mailbox from the 2003 org to the 2010 org, does anyone know how that is carried out? Does it make a copy in the new org then delete the original once all the data has copied over? Or is it a bit more complicated than that?
Question2: Rather than migrate the AD accounts, we are creating new AD accounts in the second forest and re-ACL'ing. I'm curious - when Quest migrates the mailboxes, how does this affect the msExch attributes of the two AD accounts?
