I'm looking to upgrade from Server 2008 R2 to 2016. My NPM is 12.0.1 with other modules that I'm looking to upgrade. How would I go about this? I figure that the Server will need to be upgraded first for sure but my main concern is what happens to all my backups? Do I need to do a fresh install of NPM since I have a new OS or is there an easier way like migration? I'm looking for the most painless way as possible. Thank you in advance.
