I started a migration from SBS 2003 to SBS 2011 a few months ago (I have done this successfully several times in the last 3 years). I ran in to a problem with public folder migration, wherein the replicas would never move to the new server (and I mean never). This is a small installation with small public folders (i.e. the OAB has maybe 100 entries in it, not really anything else stored in the public folders).
I got tired of playing with it, and the new server was running OK with the old one still there, so I left it alone for 2 months. I picked it up again this week, and still can't get the public folders to move. I am running in to problems with the OAB not updating on the Outlook clients properly; if I try to download the OAB I get the following error:
Task 'Microsoft Exchange' reported error (0x8004010F) : 'The operation failed. An object cannot be found.'
I read several articles on forcing the Exchange 2003 box off the network, but I decided to try reinstalling Exchange on the old box first. That failed also, and now I can't start most of the Exchange services, and if I try to use SBS 2003 setup to repair Exchange, I get "Multiple components cannot be assigned the requested action(s) because: You cannot install this product on a computer running Windows Professional". If I try Remove, I get "Setup encountered an error while checking prerequisites for the component "Microsoft Exchange": 0X80072030 (8240): There is no such object on the server.
I just want to get this thing off the network and fix all of the Exchange components on the new server to take over. There is really nothing left on the old server that I want.
HELP!
