Hello,
I'm planning on upgrading our Exchange 2000 server to 2003 and wanted to get some advice on my plan. First, I'll be upgrading AD and the DCs to 2003. My plan for Exchange is to
1) Install a Exchange 2003 server on one of our W2K3 servers in the same admin group of the Exchange 2000 box.
2) Move mailboxes to new Exchange 2003 box.
3) Rebuild original Exchange box to W2K3 and Exchange 2003
4) Move mailboxes back to original server
5) Remove secondary Exchange box.
Sound like a workable plan? Any caveats I should be aware of? Seems deceptively simple which always worries me. Thanks for the help.
Matt
