We have a Zimbra server having 500GB as it's primary message volume and mounted as messagevol, and 750GB as it's secondary message volume and mounted as hsmvol.

Can we migrate this Zimbra into another new empty Zimbra server just by doing a full restore from the existing Zimbra build-in scheduled full backup? Or do we need to recreate all the domains and their email accounts first before doing the full restore?

Also, for the restore to work, must the primary and secondary volume be of the same folder/directory name? And will it get restore to messagevol and hsmvol just like the current Zimbra structure? Or will all the backup get restored to the primary message volume such that the new zimbra primary message volume must be 1250GB so that it can contain all the content from both messagevol and hsmvol from the backup?
