Since I'm paranoid and I know that "if something can go wrong, it
will" ;-) I'd go the extra mile and create an archived backup (perhaps
compressed with 7zip / p7zip, using maximum compression -mx9
parameter) of the .vdi / .vdk or whatever disk image file you're
using, before making the upgrade.

Just in case, you know. ;)

Exporting the machine in its current state as an ovf "appliance" and
storing it on another (perhaps external) hard drive is also a good
security feature.

But the above is just adding layers of redundancy. "just in case" ;)

So, yes, I can't think of anything else besides what you proposed for
a Linux distro version upgrade...
