vSphere environment migrate VMs

Hello,

I have an environment with one datacenter, two clusters(one old and one new).
The old has one dvswitch and the new has one, config differs because old dvswitch uses LACP and new does not(10Gb).

I have therefore configured a new dvswitch with portgroups for the new cluster. Both clusters have presented the same volumes and share datastore clusters.

What would be the best solution to migrate VM's, as you can't migrate a live VM because it's bound to the old portgroup. The migrate virtual machine networking is not applicable either because I need to migrate both the VM and the networking for the VM.

Create a temporary Standard vSwitch with identical labels, e.g. VM Network, you'll then be able to Migrate.

When the VM is on the final host, switch the networking to a dvswitch portgroup you require,

Hi Andrew,

When you say migrate, are you referering to migrate virtual machine networking or vMotion? I tried creating a standard switch on one of the new hosts, but I'm receiving a red error stating that Network adapter 1 uses distributed virtual switch with uuid "xx xx xx" which is not accessible.

There is NO requirement to use any physical nics, for the move! (vMotion).

Clearly it will mean downtime for the VM, for a few minutes.

I created a portgroup on source host, reconfigured the VM to use that one, ran vMotion and then connected the VM to the correct portgroup on the destination cluster and dvSwitch.

Yes, that worked very well. I was hoping to not have to configure the VM(disconnect networking) before the vMotion process, but I don't think this will cause too much down time anyway.

I am not discontinuing the old cluster, just moving some of the VM's to the new infrastructure. Already seeing great benefits of multi-nic vMotion on 10G.

Thanks for the help.
