[Question] Migrating and Upgrading Proxmox to New SSDs on Poweredge Safely (lemmy.ml)

submitted 3 weeks ago by [email protected] to c/[email protected]

8 comments fedilink hide all child comments

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?

I have a remote pbs but the backups aren't current because there was a connection error. I have Proxmox backups locally to a USB thumbdrive. That's what I was going to restore from.

I would say that is not the best way to keep/restore backups as you are missing the integrity checking features of a true backup system. But honestly what really matters is how important the data is to you.

When I say local I mean automated PVE backups the same as it would be through PBS. If that makes any difference.
