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.
