I'm running 5 exchange 2016 on Windows2012R2 with one DAG in 2 sites. Since Windows2012R2 reached end of life, I have to upgrade Windows2012R2 to windows server 2016. What is best route?
My thinking is to take 2 servers off DAG, remove database copy, upgrade OS to win2016. Create a new DAG, and start migrating mailboxes to new DAG. Do the same for remaining servers one at a time.
Any advice is appreciated.
PS: the server hardware doesn't support win2019 and above. win 2016 is only option.
