I have an existing exchange 2007 server installed on a win2k3 server on a win2k3 domain. I am wanting to migrate it to a win2k8 server on exchange 2007. I have installed the server 2k8 server and put it in the domain. I am thinking I can now install the exchange 2007 server on the new 2k8 server and then move the mail accounts from exchange 2007 on the 2k3 server, to exchange 2007 on the new 2k8 server. Just wondering if the two copies can coexist ok for the variable number of days it will take to move from exchange on the 2003 server.

ok. thanks. One installation of exchange 2007, the one on the win 2003 server, is at exchange sp1. The newest installation of exchange 2007, on on win server 2008, will be exchange sp3. This can still coexist good with this arrangement.

Latest SP etc. Update the existing E2K7 to SP3 before you install the new E2K7 server. You don't want to mix-n-match. Other than that you're okay. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Heard some people have had a pretty rough time installing sp3(bsods, owa not working, etc..). Any commonality to these issues or is it random.

BSOD happens because of processes that run in system-mode. Exchange runs in application-mode. I doubt you'll find very many "we installed SP3 and everything works great!" posts in newsgroups/forums. Nobody complains when it all just works. Most of the "it doesn't work" things you read about are misconfigurations/tweaks/missing patches/lack of testing/etc. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Yes good point. The current exchange 2007 server is at exchange sp1. Is there any issue in going straight from exchange sp1 to sp3.

None that I know of. Just be sure to install the latest rollup after updating to SP3. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
