One of our customer raised the below environment:
Mailboxes are already moved from on-prem to Exchange online by Hybrid
MX still points to on-prem.
Customer want to keep on-prem Exchange server to do some administrative tasks later, but they'd like to move it to Azure Data center.
1. Can they move on-prem exchange to Azure data center and then point the MX record directly to Office 365?
2. If they can move on-prem exch to Azure, do they require on-prem EDB also to be moved to Azure data center to avoid any functionality issues (or)
Is that okay to get rid of on-prem EDB and move just the on-prem server? If we get rid of on-prem EDB will it affect certain functionalities for moved users?
Any pointers would be of great help.
Many thanks in advance.
