Is there any simple way to replace the OS version on the recovery
partition? I have obtained a Mac Mini 2012 that apparently shipped
with Mountain Lion and no matter what version of the OS I update to the
recovery partition remains Mountain Lion.

I want to do an clean, internet restore to at least Mojave. On another
machine running High Sierra I notice that the recovery partition offers
3 options for restoring over the internet: restore latest compatible
system, restore last loaded system, and restore the system originally
shipped. The Mountain Lion version only offers to restore Mountain
Lion over the net.

I am aware that I can download updates from the Apple Store, use USB
sticks, etc, etc. but it's much simpler to just do an internet restore
on a reformatted disk.

When I upgraded from 10.10 to 10.13, I did a new install on a new wiped drive.
Then I migrated from my old drive to the newly installed 10.13 system. That
gave
me a APFS system with a 10.13 recovery volume.

AFAIK, just upgrading a 10.8 system to 10.13 or higher won't upgrade the
filesystem
to APFS on a SSD. Of the three backup solutions I use, Carbon Copy Cloner
won't
upgrade the recovery volume unless you're cloning the old system to a new
drive.
Then it asks for the "Install MacOS" app to extract the recovery partition on
the new
drive. SuperDuper! doesn't do this but it's good for cloning existing drives
to backups
for my daily.

So to do your install, on a blank drive, install a new copy of 10.11 and do a
migration
from your old drive. That should give you a current recovery volume and a APFS
system drive.

Note that this tool works for disks that are formatted as HFS+ to create
another partition but don't work for APFS formatted drives. The OP wanted a
way to create a Recovery Partition on High Sierra which, if installed on a
blank SSD drive, will be APFS. If they upgrade an existing system (e.g.
Mountain Lion -> Hight Sierra) I don't know if it will touch the existing
recovery partition. Cloning the old drive running High Sierra to a new one
with Carbon Copy Cloner will also offer to create a Recovery Partition if the
"Install MacOS" application is around.
