How to uninstall and decommission MS Exchange Server 2013?

This is using a co-exist of MS Exchange 2013 and2016 Exchange Organization. Both Exch servers are multi-role. Exch2k3 server has been installed and working for the past 3 years. Exch2k16 server was newly-joined 2 months ago. All user mailboxes have been moved to Exch2K16. Mail sending/receiving and other exchange operations are working fine.

Now, we want to disjoin and decommission this Exch2k13 server. How to do it properly? My experience on removing exch2k10 was rather scary, as uninstalling didn't turn out smoothly. Most of the time, I have to "force" uninstall.

Thanks in advance.

you also need to move all arbitration mailboxes from 2013 server to exchange 2016 database, that is an important step
Your SPF record should include 2016 server public IP, that is an important step
If you also have public folder, that also need to be moved to 2016 server
I believe you already have pointed MX to new server
