Question Migration within Proxmox from Debian 9 to Debian 11

[tacriela]

Server operating system version

Debian 9.13.0

Plesk version and microupdate number

18.0.44

I want to migrate from Plesk Debian 9 to Plesk Debian 11, but since I only have one server with limited space, I dont know how/if this is possible. How would the migration work if I have a VM hosting environment (Proxmox) and I open two VM's on which I install Plesk? Will this be possible?

ideally you would want to have both running and do a migration. If you do not have enough space then the next best thing would be to use plesk backup to make a full backup of the server, nuke the vm, build new vm with everything up to date, then import in the backup file.
