PBS Pro v21 licenses

I am about to upgrade our install of PBS-Pro from V19 to the latest version 2021.

I have generated the new style licenses used by 2021 but I have noticed that in the license file the VERISON line says 20.0

Will these licenses work with 2021 ?

As I'm doing an upgrade and need to keep downtime to a minimum I can't risk installing 2021 and then finding that I need updated licenses as well.
