Have a 2008R2 running as a member server and would like to move VM to another 2012 Host.  The configuration is as follows:
Both Hyper-V hosts are running Win 2012.
Running 2 AD domains on different subnets and without any trust relationship.

Host A =  AD DomainA (ABC.local)--- Member Server (want to move to Host B)

Host B = AD DomainB (DEF.local)

Can you disassociate the member server from Domain A (make it a workgroup server) then export the VM, import and start the VM on Host B then add it to Domain B after changing network settings?  Will that break MSSQL Express?

Probably will break the application running on the member server and have to check with vendor.

Yes, you can remove a server from one domain (by converting it to Workgroup) and add it to another domain. However, this could break SQL Express and the application if they are installed and running with domain account. Before removing the server from the domain make sure all services are running under local computer account (even temporary, after joining to the new domain you can switch them back to a domain account for better security).

Moving a VM from one host to another is straightforward: Shutdown the VM, make sure it doesn’t have snapshots, export it and import it on the new server (select to copy all files if you want that they go into the default locations). The only catch here could be if the second host runs 2012 R2 and not just 2012. Hyper-V Manager of Windows Server 2012 R2 cannot import virtual machines exported from Windows Server 2012 or earlier. In that case, you will have to create a new VM by using the existing VHD/VHDX files.
