I want to decommission our Exchange 2013 platform which we have in Office 365 Azure AD sync environment, we had a DAG set-up and now down to single Exchange 2013, this is post cut over migration to Office 365 (we used CodwTwo), we want to neatly clean and remove Exchange 2013 without deleting users etc.. I can't find any real documentation for this, quite mixed opinions as some suggest to leave Exchange in existing cloud.
Is there a process to do this cleanly? We have Azure AD Sync in place and all working 100%, just need to remove Exchange cleanly.
Thanks,
