Server migration devices not enrolling new server

Server migration devices not enrolling new server

We just moved our ManageEngine MDM from Server  2008 R2 to server 2019. I was able to back up and restore the database to the new server and it sees all the devices.  We are managing around 100 iPads on the server.

When in Inventory and Scan devices they will not check in on the new server.

I tried to delete the profile on a iPads and try the self enroll I get the following errors:

      1. Profile failed to install
      2. New Payload doesn't match with old one.
