Updating CoreELEC on Ugoos X3 Cube running Dual Boot Firmware

I mainly use my X3 Cube as a TVHeadend server. Is there anything special I need to do if I’m running the Ugoos Dual Boot firmware?

I’m on CoreELEC 20.5 Nexus so I’ll have to manually do it with an update file. I should just copy the 21.3-Omega NG file to the Update folder and reboot, correct?

My main concern is stability as a TVHeadend server, should I even update? It’s been running pretty good but occasionally has glitches. Should I be concerned about breaking any add-ons going from 20.5 to 21.3?
