Moving a Proxmoc 256 MB NVMe install to larger NVMe (lemmy.ml)

Finally managed to get my hands on 2x1TB NVMe's. Budgets are tight these days ... :-) They are Crucial P310 ... hope they are reliable, although I suspect nowhere near Samsung stuff.

I have a little Proxmox installation running a VM on a 256GB NVMe, which as you can imagine is tight. Is there a way of cloning this installing on one of the new NVMes?

Reason why I have 2x new NVMe is that I want to eventually get myself to Proxmox HA, so that the two machines (two little Optiplex 5070, one of which has the 256GB install) provide me with redundancy.

First thing is to clone the 256GB install to the larger NVMe. Would it be an idea to go this way: a) install 1TB new NVMe on spare Optiplex b) install Proxmox on this new machine c) find a way to replicate the whole 256GB install on the second machine (need to read the docs to see if/how this can happen) d) once second machine is up and running as a clone, remove machine with 256GB (current machine) and install the 1TB NVMe. e) do the same above process the other way around.

Do you think this will work or am I going to hit a wall? Is there a simpler way of doing this?

Not as tight as I was imagining a 256 MB installation to be.

I know nothing about promox, but because it's quiet in here, I imagine cloning the original drive for the original system then expanding it to take over the whole drive is the easier thing to do, it's a fairly standard process and generally nondestructive because you can just put the old drive back in if something breaks.

So, I would probably go e) unless you really want to set everything up again from scratch (which is sometimes nice to do)
