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: [https://docs.inductiveautomation.com/display/DOC80/Setting+Up+Redundancy](https://docs.inductiveautomation.com/display/DOC80/Setting+Up+Redundancy) ---
