Hi guys,
I have only one Exchange Server 2010 on premises: Version 14.3 (Build 123.4) with the folowing roles installed: Hub Transport, Client Access, Mailbox in Hybrid Environment with Office 365.
I use Microsoft Azure AD Connect 1,1,751.0 for AD syncronization with the Cloud.
I have migrated all the mailboxes an I would like to get rid of the on-premises Exchange Server.

I have read many articles on this and everyone approach the decommissioning in a different way, most articles I have found also suggest to keep the on premises Exchange.
After having modified the public DNS records to point to the cloud (MX, autodiscover...etc..) and moved all the mailboxes to the cloud  what are the steps for a clean decommission of the on premises Exchange?
I assume that I should somehow modify the AD schema to "clean" the unwanted Exchange attributes right?
If yes, how?
I assume I should keep  Microsoft Azure AD Connect to syncronize passwords and AD attributes, right?

As you guys can see I'm quite confused, hope someone could spare some recommendation for me to go through the process

Thanks a lot
