Hello, I need your advice
We have an Exchange 2007 server Ver 8.1 (build 240.6), running on Server 2008.
The Operating system has become unpatcheable, and it does not matter how many times I run the sfc /scannow and the sp2 prep pack, it still will not sort itself out.
I have come to a crunch point, as Backup exec kept locking the server up whilst backing up, and had a major or caused a major RPC memory leak, so uninstalled Backup exec, and tried to install Windows Backup, and that won’t happen either.
So after deciding to rebuild and very little ability to backup, I have borrowed a server, put Windows 2008 64 bit (not R2) so it is identical to the current server, and then installed Exchange 2007. I have left 2007 unlicensed as I should have this all finished in 2/3 weeks.
I have been able to move a couple of test mailboxes to the new server and able to send and receive external email.
Questions (as I have not had to do this before, so looking for reassurance from the Experts)
1) move all mailboxes, re-home the connectors on new server, set up Public Folder replication ? Have I missed anything
2) Uninstall – Decommission the first server, are there instructions, as this is the first exchange server in the site and AD Forest
3) Rebuild, re-install the OS, Reinstall Exchange, Apply Licence Keys
4) Move everything back to original server, ensure it all works, and then decommission to remove the 2nd server
Any links to Trustworthy articles on how to do this would be much appreciated, as this is making me as nervous as hell, and with no working backup, Time is not on my side, otherwise we are going to end up in log floods, and all sorts of Nasty stuff.
