At this point we have migrated all the things and we are ready do decommission the old Exchange 2013.

This is our situation now:

Now before uninstall, we need to remove the mailbox database on Exchange 2013:

Get-MailboxDatabase

Remove it:

Remove-MailboxDatabase -Identity Exch-2013

Don worry about this error… (see this article)

Go to the control panel and uninstall the Exchange 2013.

Now in the case of queued messages use this command to see the situation ad read this good article :

Get-Queue -Identity Submission | Select Identity,Status,MessageCount

So now uninstall it.

Done!

Now reboot, remove from AD the server, power off it, move its IP to the new one (exchange 2016) as a secondary address .

That’s it!
