Gateway Redundancy, Master and Backup Operating Systems

Can I have different server OS versions between Master and Backup gateways when setting up Gateway Redundancy? so can one server be a MS 2012R2 server and the other be a MS 2019 Server?

Recommended to be as similar as possible (mostly easier to debug), but an combination of OS is possible.

Details on the docs page:

Thanks for the info and quick response.
