SCVMM Live Migration to different cluster can't switch network for VM

Question

Hi
Our design is that each cluster has its own logical switch. We previously had all clusters connected to one big logical switch, but when adding a new VLAN, it took almost 15 minutes to update all the hosts. Looking at the powershell script for adding a new VLAN, I can imagine why.... you see how it first reads ALL the VLANs, and then re-adds them all. With 20 clusters, 300+ hosts, this takes some time.

Therefore we decided to move to a logical switch per cluster, but when performing a live migration between clusters, we don't get a question as to which network the VM should be connected, so we can't point the VM to the new logical switch. The only way we've been able to do this, is to first make the VM no longer high available, removing it from failover cluster manager and then use Hyper-V to migrate the VM to the new cluster and add the VM to failover cluster manager again. Not a desired methode.

Is there an other way to move VMs between clusters and then also switch the VM network?
