I have searched the internet, but mostly found stuff on Exchange 2010 or from 2003 to 2013, etc. I want to make sure we run through this correctly.
We are also migrating all of our environment servers from 2008 R2 to 2012 R2. Is there a specific order you would do this? Domain Controller first and then other servers after? I'm seeing people also recommend staying away from "in-place" upgrades and instead building brand new servers. Is this the consensus across the board even for something as simple as a file server?
