Hi,
this is our Scenario:
Server:
2x Windows Server 2013 running Hyper-V 2013
Each Hyper-V Server runs one Exchange 2013 CU3 15.0.775.38 November 2013
Clients:
Windows 7, Office 2010
Windows Server Active Directory, DNS, DHCP
Task:
We want to upgrade our Exchange Server to the most recent Version.
Problem:
The last time i tried to upgrade the Server, i completly lost the Exchange Server AND (!) all Active Directory Users/Groups.
so actualy im realy scared to touch anything.
afaik the install process will be like: start setup ( which is pretty much a new exchange installation ),it will remove the installed instance, reinstall the new version.
Questions
if every install is like a fresh install, do i have to reconfig all my exchange server settings ?
should i shut down both exchange server for "backup" reasons or does the fresh installed server
"need" the 2.nd server online ?
do you have any clue why all AD Users/Groups etc where removed when the former installation failed and how
can i prevent that from happening again ?
do you have a step by step howto upgrade to the newest exchange server version and which version would you recommend as i can see there are some big problems with the most recent one ?
thx in advance.
