Decommission EXCH13 after migration to EXCH19 RRS feed

  • Question

  • Hello!

    A few months ago we configured an on premise Exchange 2019 server and then migrated our mailboxes to a 2013 instance(2013 also on premise).

    Our 2013 server has been physically powered off for three months. I would like to understand the steps i need to officially decommission it, remove any connections, and uninstall it. My goal would be to then raise the functional level of our domain to 2016 version.

    Can somebody please help me understand what the steps are to decommission this 2013 instance?


    current exch version:
