I want to upgrade my AWS EC2 instance to 2016 to make use of Docker containers.

Will I lose my 2012 Server configurations - IIS, etc?

  • I assume you have a backup of the configuration file, no? Jan 7, 2017 at 11:03

    I'm voting to close this question as off-topic because this is about server configuration which is off topic here and should have been asked on serverfault.com

The very first thing to do as @Stephen Ostermiller points out is to do a full backup of all your configuration settings. Now having said that if you do an in place upgrade from Server 2012 to Server 2016 then you won't lose any configurations except for those that are no longer supported or needed within 2016.
