[Server 2012R2 / 2016] Do i need to use adprep or not?
Hi, this is my first post.
I plan to upgrade a network with multiple windows server 2012R2 to windows server 2016 like this:
First I add 2016 servers (which will then be at the 2012R2 AD level) and move functions to them.
I make some of the 2016 servers to DC (still 2012R2 level).
I’m demoting and phasing out 2012R2 servers that no longer have any functionality.
When all 2012R2 servers are disconnected, I raise the AD level to 2016.
My question is: Now that I’m going to install my first 2016 server and make it to DC, do I need to run “adprep” on it? If so, how?
Exactly what does “adprep” fill for function? What does it do?
Grateful for all the answers.
