I want to decommission the exchange 2013 server in a hybrid configuration that also includes exchange 2016 server. I want to retain the the exchange 2016 server. Exchange mailbox databases have been removed from the exchange 2013 server. Is there a recommended step by step procedure on how to complete decommissioning the exchange 2013 server?
Thank you.
