New drive for Proxmox boot - Move existing install or start again?

I'm going to be getting 4x1TB SSDs soon to replace the boot drives in my existing PVE hosts, and i'm not sure on the best way to go about swapping my old drives over.
I have a Dell R220 and Dell R210 II. Both Dell's only have 2 x 3.5" drive bays, but I also have 2 x 2.5" SSDs sat in there too, as there is still enough physical space...but that's kind of irrelevant information

Both hosts have Proxmox Backup Server installed, which backup to a 2x12TB NAS. I know I shouldn't install PBS on the host OS, but I had no other choice.

Background on the hosts:
---------------------
Dell R220 - 3 containers, 2 VMs
2 x 500GB SSDs - ZFS mirror (mirrored after install, so only .part3 is mirrored - not the boot partition)
-PVE
-VM OS partitions

2 x 8TB HDDs - ZFS mirror
- VM Data partitions
-------------------
Dell R210 II - 1 container, 3 VMs
1x 120GB ZFS
- PVE
- VM OS partitions

1x 1TB HDD LVM-Thin (wanted LVM-thin for snapshots) - Data on this is disposable and can be downloaded again
- VM OS/Data partition

2 x 4TB HDDs - ZFS mirror
- VM Data partitions
------------------

The plan is to get 2 x 1TB SSDs for each host, and I thought if I just re-install PVE on both hosts and set up the zfs mirror during install, then I can set entire drive to be mirrored instead of just the data partition ( i think that's how it would work?).
I was then going to re-install PBS on each host and restore the VM's and containers.

What I would prefer to do is just copy the old PVE partitions to the new drives, so i don't have to restore the data and set everything back up again...but that leaves me with the annoying problem of not having the entire drive mirrored, so I can't win either way.


What would you guys recommened I do in this instance? Thanks!
