Migrate windows from Xeon Silver to older Xeon or AMD?

Greg_E

I'm making a plan to cover a situation and it brings up what might be a stupid question. Migrate from newer hardware to older harder or "smaller" AMD hardware?

In a stroke a genius, we are possibly cutting my tech room in half, cutting out concrete at the end of one room and building an extension into my tech area (TV studio equipment and server equipment). This will of course generate massive amounts of concrete dust. It will also probably shut down the cooling. And will give us no room for expanding any tech equipment.

My choices are shut down production servers one by one and move them to another room where I have connections. Then reverse this when the construction is done. A big job that I'm not looking forward to doing.

Pull my lab apart and put that in the other room, two parts to this. Each option has 3 hosts and 1 storage.

Part one is pull my "big lab" apart which is HP DL360 gen8 servers, move those, join the pool, and migrate vms and then migrate XCP controller. This would be going from Xeon Silver (10c/20t) to Xeon E5 v2 processors (20c/40t).

Part two would be pulling my "mini lab" down and moving it to the other room. This is HP T740 thin clients, core count is my concern here with AMD v1756b 4c/8t processors and half the ram at 64gb. This mini lab all fits on a single rack shelf and much easier to move.

The work load from the VMs is pretty light, so I think I can over provision the T740 and it will be OK. I could also add more T740 if needed ( or T755 if I'm lucky, 6c/12t).

I'm not sure which of these choices is going to make the most sense for 3-4 months of use. The other room is in another building and an extra 3 switches away from my core switching stack.

Hi,

I read it quickly, but it's likely Warm migration is the solution you need.

@olivierlambert

I was looking for a way to mark this solved, can't find it.

I haven't moved things, but after migrating my big lab to my mini-lab, I'm confident that the warm migration is the way to go. It was fast and seamless as long as you have the right network adapters set up. I had to fool with one of my networks to make a VM function, but that was certainly something I overlooked while setting up the mini-lab. A little testing before moving the VMs should make this go easily if using the old servers is the option for this project.
