Upgrade storage Hard disk?

Proxmox 6.1-3
I have OS (boot ) on ZFS raid 1
then 3 x 1TB HDDs
they are not in a pool/raid array
I want to swap out one of the storage drives for a 2TB drive (maybe all of them if I can find my drives in the shed!)
Do I back up the VMs on the existing drives (I have a NAS mounted as storage for backups), remove them, install new and then restore?
There must be a step in the middle of that lot to tell the OS the HDDs have changed?
