we are migrating from exchange 2003 to 2010 SP1.
I am wondering what is the "better" idea: to virtualize all roles or to mix it up,expecially the mailbox server role. We have about 100 users.
My idea is to have the CAS/HT virtualized and the MB server (which will be a 2 Server DAG)
Any suggestion,thoughts and best practices? Useful info is appreciated
