I am looking to upgrade an environment from Exchange 2003/Server 2003 to Exchange 2007/Sever 2008 (not R2).
Currently the environment runs in a VM under VM Ware.
I suspect the new VM might require more resources and I have had the Exchange Profile Analyzer tool run on the environment. How can I take this data and project what the new environment needs to be (especially RAM and CPU units?).
Any ideas appreciated.
Note that there are about 100 mailboxes with about 50 active ones. The server also supports OWA but has no other uses.
Thanks
