How to do a Full clone a Proxmox System?

Hi there!

I'm wondering if theres a way to make a full clone of a Proxmox System.
I have an NVME 1tb with My Proxmox System and some VMs inside, but I'm planning to migrate to a bigger one.

So the plan is to buy a 2tb NVME Drive, an USB NVME case and do the clone.

But I don't have any idea of how to do that.

Thanks
