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

submitted 2 months 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?

This is a question probably better-suited for one of the Proxmox communities. But, I’ll give it a try.

Regarding your concerns about new SSDs and old VM configs: why not upgrade to PVE8 on the existing hardware? This would seem to mitigate your concerns about PVE8 restoring VMs from a PVE7 system. Still, I wouldn’t expect it to be a problem either way.

Not sure about your TrueNAS question. I wouldn’t expect any issues unless a PVE8 installs brings with it a kernel driver change that is relevant to hardware.

Finally, there are several config files that would be good to capture for backup. Proxmox itself doesn’t have a quick list, but this link has one that looks about right: https://www.hungred.com/how-to/list-of-proxmox-important-configuration-files-directory/
