Migrating PVE to new server hardware

[Maurice]

Currently I have PVE 6.4 running on an HP Microserver Gen8:
- PVE running on an SSD (ext4)
- VMs stored on a ZFS pool of 2 HDDs

I want to migrate this setup to a HP ML310e Gen8 v2.
Also I wan to upgrade to PVE 7.1.

Questions:
1. Would you start a fresh install of PVE 7.1 on another SSD and transfer the ZFS pool to the new system? How would you recreate the VMs in the new install?
2. Would you to just transfer the SSD and HDDs from the old server to the new server, lock, stock and barrel? Would this work? Any pitfalls?
3. Any other options?

Hello,

i would just transfer the SSD and HDDs from the old server to the new server.

1. backup your old configs and vms, if you do a fresh install.
2. On EFI-Systems make sure to update grub via a live linux with chroot, if not bootable.
Also check hardware-settings like CPU-Types for the VMs.
3. not really
