First off our current environment:
3 Windows 2000 Domain Controllers
3 Exchange 2003 servers
1 Exchange 2000 server (will be retired soon, just used for SMTP server for some old scripts now)
**These are all on individual boxes. We have 2 new 2003 member servers ready to promote once we get the 2000 domain ready for AD 2003.
We are getting ready to upgrade our domain to Windows AD 2003 but have a couple of questions regarding ADPREP /domainprep & /forestprep for both AD and Exchange. Ive been reading articles but most have to do with upgrading Exchange 2000 while upgrading the domain. We already have Exchange 2003 running in our 2000 AD domain.
So Im confused about what order to run the separate /forestpreps (exchange and AD). Do I need to do the Exchange 2003 /forestprep before I do AD /forestprep? Would the Exchange /forestprep have already been done when it was installed or is that impossible since were still only on a 2000 domain? In that case, do I run the Domain /forestprep & /domainprep before I run it on the Exchange servers?
Just want to make sure I have everything in the correct order before I pull the trigger. Any help/advice would be greatly appreciated!
