migrating from one physical data center to another (across the wire)

[drivera01]

we have a couple of thousand vms that over the next few years need to be moved from datacenterA to datacenterB. We have a good pipe between both datacenters which are X miles from each other, but in the end we would have to come up with some creative solutions.

Once the vm's are powered off , the whole migration can take place. The vm's will not be powered back on until they are placed on to their final resting place datastore.... but this is what I am thinking about.

I was thinking of using a NAS based transitional datastore, initially mounted on the source cluster, moving the vms to the transitional datastore than mounting the transitional datastore on the target cluster where we are migrating to, then move the vms to their final resting place datastore...

Is this a feasible option?

if not, im all ears on recomendations how to actually move vms in mass quantity....

thanks

Hi

Welcome to communities.

yours 2nd option is good but NAS may perform little slow .

ya I expect the performance to be extremely degraded. The best I can do is start with a SSD datastore to hopefully counter-balance some of that degradation.  Since I don't plan to actually run the vm's on that datastore.. Hopefully all goes well.
