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?
