SBS4.5 to SB2000 upgrade
Posted on 2003-10-30
I would like some assistance with information on upgrading SBS 4.5 to SBS 2000..... and any pitfalls etc. that anyone here has had between them.
Upgrading in place is not an option due to new hardware being required which leaves as far as I can see the "start from scratch" migration technicques described in MS articles 278439 and 290603 etc. involving pulling everything off and starting again on the new box.
With a non SBS network I could add a NT4 BDC then take it offline and upgrade that to W2K with Active Directory and make a mixed-mode domain but is this even possible upgrading using a SBS 2000 CD? Then at least I'd not have to re-create all the accounts and SIDs would be kept the same etc.
If I had done that are there any issues you can think of with exmerging the Exchange 5.5 folders into a server with a new name or IP address running Exchange 2000?
One concern of mine is with the recommended migration method clients are going to have the same username but with new SID on the new domain (but the same domain name) and will therefore get a new profile on their W2K / XP PC's and lose all their settings etc. which might cause unknown problems with existing apps (though should be OK...)
I am MCSE (not that always means much) and fine with standard W2K / NT networking but haven't had much contact with SBS and all it's nasty little restrictions and don't want to trip up if I go down a different route to the MS suggested one.
Any advice, suggestions, gotchas etc. appreciated, even if it is only to part of this. ASAP if poss please too as I'm doing it tomorrow!!
Points aren't a problem... will split up or award more elsewhere if needed.
