I have a Exchange 2010 migration(to exchange 2016)
and my customer was impatient and has installed this morning Exchange 2016 without prerequisites(Unified Communications Managed,prepare AD,windows features..)...but didnt restart exchange 2016 after installation.
What should I do now?
Uninstall Exchange 2016,install prerequisites,install Exchange 2016 again?
Should I continue migration???
Any advice,hint please????
