Hi PS_Exchange_Adm 

1-you will need also to update autodiscover record to point to exchange online and set it to null in the on-prem environment.

2-use Remove-hypridconfiguration command to remove it from Active directory.

3- you will need to decide if you will keep directory synchronization or not.

    Thanks Deleted.  the autodiscover record has already been pointed to their Office 365 tenant and they will continue to use directory synchronization with their own on premise AD forest.  Sorry, I should have mentioned that in my original post.  But I appreciate the additional insights.  Looks like I wasn't too far off on my original plan.  I'll post back here after I complete the separation and provide feedback in the event any additional items are uncovered or issues arise after I'm done.
