I have a windows small business server running sp2 and I need to migrate this to a full blown version of windows using the small business server 2003 R2 transition pack.
In order to do this you are supposed to do the following:
1) Uninstall sp2 if it exists
2) Upgrade to SBS 2003 R2 form SBS 2003
3) Run the SBS 2003 R2 Transition pack to make it a real exchange/windows 2003 domain.
4) The entire goal... migrate mailboxes to a new exchange 2007 server - not something you can do from SBS environment apparently.
The problem is the very old server was running out of space and I deleted the uninstall files for SP2 and unless I can get back to SP1 I am unable to do the R2 Upgrade -> Transition pack etc.
I cloned the old raid partition to a new TB drive so I have lots of space and a complete backup clone on another TB drive so I can really go nuts on this if need be. I was going to try to an in place upgrade to with the original media SBS media over top of my partition but it does not seem to give me the options described in kb816579 (sorry - I don't have the cred to link..) specifically once I select the partition there is no option to repair - only to delete it and start fresh.
Any thoughts would be really helpful - am trying very hard to avoid migrating all workstations to a domain set up from scratch.
