Hi, a while back I was able to do this, but cannot any longer due to 'no release file' for buster, so guessing the sources/debs have been removed? Its the first part, going from 6.3-9 to 6.4 that I'm stuck with. I know you can use the pve6to7 method from 6.4 onwards. Any way to get around this without doing a fresh install? I know they're older versions and I don't want to stay on that version, so I'm trying to move off of it to at least 8, but can't do this part. Using this in sources.list.d/nopvesub.list:

Code:
deb http://download.proxmox.com/debian/pve buster pve-no-subscription

Have those been archived somewhere? Thanks.

You're lucky, Proxmox recently released an archive mirror which comes in handy for your "usecase":

http(s)://archive.proxmox.com/debian/pve

Add that repository to your sources and you should be able to finish what you're trying to accomplish.

Thanks, I'll check it out in the morning.
