Hi Doug,
No, it will not automatically discover the VMs running on the hosts.
Because you are creating a new database with new installation. You have to re-add the Hyperv Hosts to SCVMM.
As old agent is installed on the Hyper-V hosts, you may have to re-install agents on the servers.
Then it will discover the VMs.
Sincerely,
Murat Demirkiran
