Windows Admin Center - Vmware migration to HyperV

We have a vCenter (multiple hosts) with about 30 VMs and need to migrate them to a single HyperV host. I installed the Windows Admin Center and the other components (https://learn.microsoft.com/en-us/windows-server/manage/windows-admin-center/use/migrate-vmware-to-hyper-v). I migrated 2 servers, one at a time, and both seemed to work, though I had to set the IP manually. I then chose 2 servers to migrate both at the same time and it seems to be hung. The sync process completed successfully. The migration process for both got to 25% and has been stuck there for a day now. The disks aren't that big and, presumably most of that was created/copied during the sync process. 

I also don't see an option to stop the process or restart it. I know the VM Conversion is a Preview function, so I'm sure support it limited. Any help or direction would be appreciated.

    Hi, there is a known issue with the bulk migration process. Are you able to migrate those 2 VMs that failed earlier migrate one at a time?

      I've run into the same thing.  I was only doing one VM at a time.  Sync'd yesterday.  Attempted to Migrate today.  I see on the vSphere side it showed taking a snapshot but on the Admin Center side stuck at 25%.  I did several test VM's and one production VM prior to this and they worked.  I did not use the optional tools to remove VMware Tools or handle Static IP's since in testing I found those both made the migration stall at 25% as well.  My session between Admin Center and Vcenter may have timed out during the process.  Is there any way to start it over?
