Sorry, bad pun.
Here's my Dilemma. I am putitng in a new server for a Non Profit orginization. Server is a Dell PowerEdge 1900 with two Quad Core Xeons. The software was purchased through Tech Soup and includes Windows Server 2003 R2 and Exchange Server 2007. I got Backup Exec 11 with the Server and I have Symantec Corporate 9 from the old server which is running SBS 2003.
Apparently Exchange 2007 will only run in x64 environments, a fact I was not aware of until I tried installing it. I tried once before to persuade them to not get Exchange 2007 as it is new and I have never deployed before, but the pocketbook won in the end as Tech Soup provides massive discounts for Non Profits.
So now I am in a rock and a hard place. I either have to wipe the server and install x64 and hope I can migrate Exchange SBS 2003 mailboxes to 2007 and I would need new AntiVirus. Or I could try talking them into 2003 again. I also need to install the Server version of Quickbooks 2007 which does not appear to work in 64 bit mode. The workstations are mostly XP 32-bit with a few Windows 2000 machines mixed in for good measure.
