Question: Can I use dd to clone my luks encrypted lvm os drive? (lemmy.ml)

EDIT WITH UPDATE: Operation went off without a hitch! I'm now up and running with the 512GB nvme drive! Next stop is dual booting nixos, which was the whole reason for switching to the larger drive.

ORIGINAL POST:

I’ve got a laptop running Arch (btw), with a 128GB nvme in it. The nvme has two partitions. EFI boot, and a luks encrypted lvm.

I’ve got a 512GB nvme I want to swap in. I think I can clone the device with dd, update the uuids, expand the lvm, and drop in the 512 nvme, but my searching hasn't given me a clear confirmation of this. Am I correct in my thought process, or am I setting myself up for disaster?

Is it LVM2? If you need a GUI I recommend: Blivet-GUI from a bootable USB environment so as you said nothing is mounted, hope this helps!

    It is lvm2. Thank you for the recommendation! I'll check it out though I think I'm going to stick to the CLI for this one. I kind of want to do it manually.

    I do plan to work from a bootsble USB for all the dd work so that nothing is mounted/in use.
