Moving from Ubuntu 20.04 to 24.04

SYSTEM INFORMATION
OS type and version Ubuntu 20.04 - 24.04
Virtualmin version 6.1.4 - 7.0.6

Is it possible to make this jump? I tried using the full backup and restore method found here:

But I get an error saying:

Checking for errors in backup …
… this backup cannot be restored : Original parent virtual server xxxxx does not exist

So I tried:

virtualmin restore-domain --source ~nomad/backups/ --domain xxxxxx --all-features

But get the same error. I also cannot login to this instance of virtualmin, I’m assuming the user hasn’t been restored yet however the restore of virtualmin.tar.gz --all-virtualmin worked without error.

Any guidance?

The OS/version has nothing to do with that error.

Before you can restore sub-servers, you must restore their parent virtual server. If you are splitting them, and won’t be putting the parent on this new server, you’ll need to promote the sub-server to a virtual server.

The restore in question is for the parent virtual server. Is this not the command to restore the parent:

virtualmin restore-domain --source ~nomad/backups/ --domain xxxxxx --all-features

?
