I am new to server administration. I need to upgrade the windows server 2008 R2 to 2012 R2. Since windows server 2008 is a production server, I am afraid to do the in-place upgrade.
Basically I need the new server (server 2012 R2) to be the identical to the current server (server 2008 R2). And once the new server is up and running, I can take down the current server. How can I achieve that? Which of the following options is best for the solution.
Create an entirely new server and copy everything such as local users, groups, IIS config, disk permission information from 2008 R2 to 2012 R2. (using Windows server backup)
Create a replica of the current server and perform in-place upgrade on that server. (Using backup image of the first server) (Obviously, I would want the new server to have a different name and SID so they can both be active in the same network and joined to my domain.)
Which is the right way to approach the task?
