Decomissioning a single not anymore used Exchange Server 2013
About 1,5 years ago we moved all the email database to MS365 and since then used online the cloud solution. This was and is not a hybrid connection between the on-premises Exchange server and MS365. Now I want to delete all mailboxes of on-premises server and uninstall it.
I am looking at this tutorial in this relation: https://techcommunity.microsoft.com/t5/exchange-team-blog/decommissioning-exchange-server-2013/ba-p/3613793. With some differences (e.g. disabling and deleting mailboxes instead of migrating them) this seems to be a good way. But another tutorial suggests that a single server should be left for management (though this tutorial considers a hybrid installation with 2016/2019 EX-srv): https://www.alitajran.com/remove-last-exchange-server/
My question is: How do I remove (or at least minimize) a no-more used Exchange Server 2013 installation und Windows Server 2012 R2.
Thank you in advance.

After migrating all user mailboxes to the new Exchange server or Exchange Online, you can uninstall Exchange 2013 normally through the control panel, or run the PowerShell command .\Setup.exe/Mode:Uninstall. If the uninstallation fails, use Remove-ExchangeServer -Identity ServerName -Force to clean up the AD metadata, and then manually delete the remaining server objects under CN=Configuration in the ADSI Editor.
