Hi,
We have three physically networks in our Hyper-V environment. We don't use any VLAN tagging. The hyper-v hosts has one cable, one NIC(NIC1, NIC2 and NIC3) and one Hyper-V external switch for each network. The 4th NIC(NIC4) on the Hyper-V host is used for host management, live migration and so on...
The three VM networks is also defined in VMM as Logical Networks and VM network with corresponding IP Pools(without VLAN).
The goal is to move the three VM Networks/switches from 3 standard virtual switches without VLAN in my "old" environment to 1 logical switch with VLAN in my "new" environment.
Does anybody got any advice in this scenario ?
I've started creating a new Logical Network containing all my existing subnets, but with VLAN ID. Each Logical Network has it's own VM Network with a VM Subnet. I have created a Logical Switch with a uplink port and connected all the Logical Networks.
I've set up this Logical Switch on a Hyper-V host in my "new" environment and VM connectivity is working as expected. But how do I move my VMs from my "old" environment to the "new" ? The switches has different names, so Live Migrations does not work.
I can create a dummy switch on the host in the "new" environment with the same name as the switch in the "old" environment and move the VM, but after the VM is moved I have to change the virtual switch on the virtual network adapter to get a connection. Is there any other way to achieve my goal without loosing connection to the VMs after moving them ?
