Zgemma/VM newb question.


Hi guys,
New to Zgemma and Vm lines, i'm coming from the aftermath of the skybox channels dying out.

My vm line and Zgemma box are fine and working, my question is, as with the skybox we had channel lists to upgrade, is there something like that for the VM lines and the Zgemma box that we need to do from time to time? if so, how do you we do it and how does it work for this set up? or if somebody could direct me to a link I would be greatfull. Sorry for the newb question. Thanks in advance.
