With the EOL of PVEv7 and my need for more storage space, I’ve decided to migrate my VMs to a larger set of drives.

I have PVE installed baremetal on a dell r720 RAID1 SSDs. I’m a bit nervous about the migration.

I plan on swapping the SSDs, installing PVE8 from scratch, then restoring VMs from backup.

Should I encounter an issue, am I able to swap the old RAID1 SSDs back in, or once I configure the new ones are the old drives done for? I’m managing RAID on a dell RAID controller.

I also have my data hard drives passed directly into a TrueNAS VM which supplies other VMs via NFS. Is there anything I should be concerned about when I’ve migrated, such as errors re-passing the data drives to the TrueNAS VM. Or should everything just work again?

Is there a master PVE config file I can download before swapping drives that I can reference when configuring the new PVE install?

    would be a good idea to test the backups on 7, and double check the release notes, they hold just about every caveats. The 7to8 upgrade was not horrible, if you have backups, you could always attempt the upgrade after taking backups, then if successful take new backups, test, then install new drives and restore. depends on how paranoid you feel.

    If this was a production system, that is probably the change plan i would follow, but in production I would also be able to migrate VMs. I am not nearly as careful in the home environment.
