(minor edits for clarity)
Dear Proxmox people wide and far,
After deciding to get serious about my Proxmox journey I've found my first massive challenge - in an attempted migration from an old Core 2 Quad to a 12th gen Core i5 platform.
Connecting the original SATA HDD with a 2022 Proxmox 7.2 to the new platform and rebooting went without a hitch, but then I had the great idea of installing a fresh Proxmox 8 on the also-new NVME drive in parallel to the SATA drive. The Proxmox 8 installer renamed the former v7 "pve" to "pve-OLD" (details in code snippets below), and made the original v7 pve unbootable.
The catch: I had not yet backed up any of the old containers on the Proxmox 7 setup, so not being able to boot into that anymore is kind of problematic.
Following forum posts here I tried the things people with an actually-overwritten Proxmox installation had done (ie. attaching the pve-OLD LVM with the VM/LXC volumes, and basically recreating containers with identical IDs to get these back into a running state), but
Anyway, you can see my lsblk & lvs/vgs/pvs below. Ideally I would just like to migrate my vm-300 Alpine container with a few Docker images and data to the NVME drive's LVM on Proxmox 8 and take it from there - everything else was just experimental anyway and can go. Any advice on how I should best proceed? Enable a reboot into Proxomox 7 and backup/migrate, or move ahead with a "recreate and mount" approach straight on Proxmox 8?
Many thanks for any advice you can provide! Please let me know if there's any other info like required (e.g. on grub/fstab, etc), at least I've got these roughly figured out.
Cheers,
E

- I am not getting very far with it right now (networking issues, uncertainties about the original configuration, etc.), and
- I feel like just booting into the old Proxmox 7 installation, backing things up from there, and restoring on Proxmox 8's NVME-LVM would actually be a lot easier and faster.
