Hi all,
we have currently migrated a Exchange 2013 Server Cu 6 to another Exchange 2013 Server,because
of Hardware Problems.
Everything is working fine.
Now the issue is to uninstall the old one. The first attempt failed, because it asked for UnifiedMessaging File from the original setup with CU 6.
Of course it's not there anymore.
Deleted in the Registry the action und watermark keys. But no success still incompleted installation detected.
Is it possible to use a newer exchange 2013 cu and uninstall it from the command line?
Also asked the microsoft hotline for a download link cu6 but gave up after 1 hour with the incompetent hotline. No i don't wanna relicense anything, just uninstall this old server. :-)
Any suggestions?
