I was wondering at what point is uninstalling exchange from sbs2003 correct when migrating a domain to a new domain controller running 2008 R2 Standard? Would this have to be done before the 1st replication from the SBS which would still have all of the FSMO roles? Or could exchange be uninstalled after the 2008 R2 box has been added as a member domian controller and AD has already been replicated to it?
I'm just wondering if uninstalling exchange after the migration but before demoting the SBS would effectively "clean up" AD of old exchange artifacts for me. Our email is hosted and we will not be utilizing exchange in the future but if we ever do I want to be able to install it again without issues.
Thanks, Jeff Newbill

for the 'lowdown' on this you need to speak to SBSMigration.com, but the high level view is that (IIRC) Exchange should be removed _after_ the 'origin_SBS' is demoted out of the DC role, but before it is removed from the AD (which I once forgot to do).
If the migrated AD does not have Exchange, you also need to take the choice 'remove the last Exchange server from AD' while doing so, but, GUESS WHAT, such process does not remove all trace of Exchange from the AD. I believe SBSMigration.com, in their SBS03 -> 'AD not including Exchange' includes 'additional tidy up' in their notes.
If the migrated AD does include Exchange you don't take that 'remove last Exchange server' option but again, there are additional cleanup steps to remove information about the earlier version Exchange from the Exchange Organisation.
The notes from SBSMigration.com are _not necessary_. The instructions are fully available from MS, based on error messages you will receive during/after the processes. Depends on how much you value your time to find such. Is it better to wait and find the answer yourself, or work from docs that have the additional steps defined?
edit: changed a couple of 'new' to 'migrated'.
