I’ve been working on migrating our Exchange environment from 2003 to 2010 for several months. My first post about this is from April 14th, when I was just trying to virtualize our existing Exchange 2003 system. Once that was complete, I started playing around with Exchange 2010 around June or July, and had most of the users moved over to 2010 by the end of August. The last holdouts were Blackberry users. I couldn’t move their mailboxes because our BES was hosted on our original Exchange 2003 server.
