@marcoi I don't have enough context to reply. You should open a new thread to discuss it, with details about your needs (always better to explain the needs before the technical solution).
@olivierlambert thanks for the great advice And thanks to the developers for such an awesome migration mechanism everything went smoothly and quickly
The only thing I ran into (might be useful for others) is that the disk name label matters. The label [NOBAK] lets you exclude a disk from backups, which can be handy for cache disks, for example. Warm migration also respects this label.
No the old pool is fully gone. There was a risk for compromised network incl. hypervisor password. So the pool is destroyed. VMs are still available or available by backup. Need to access some of them without network to backup so data and to re-install win11-VMs without new activation. For the win11-VMs I need all the settings/data not only the VHD disk file.
And possibility to upgrade to different xcp-ng-versions for restore? At the moment the hypervisor is at latest 8.3 .iso -> so at least I think I Need to update to the latest version before 09/12/2025.
