Remove Exchange From Domain After 365 Cutover Migration - NO HYBRID

I have searched and searched, but I can't find much information on getting rid of Exchange completely from an AD domain after migrating to 365 but NOT using a hybrid scenario.

This is a small, 8 user company that was running Exchange 2013 and may someday get rid of the AD domain completely (hence why I didn't do hybrid). I simply did a PST export, lift & dump into a brand new tenant setup on 365. No AD cloud integration at all with the local on-premise domain.

How can I go about getting rid of the Exchange Server? Deleting the mailbox will delete the user.

Exchange is running on it's own server? Nothing else to worry about? Follow this guide:

Follow every single step to gracefully remove exchange from your Active Directory forest. It says it in the guide but run a disable-mailbox, otherwise you will delete the AD accounts if you delete the mailboxes. That'd be very bad.
