How is umbrel with CLN? Can I use my existing files to avoid closing channels? Also with bitcoind, will I be able to just go in and change parameters from the terminal?

I had moved to Citadel to get more customisation and then I built a naked setup but this makes me want to come back to Umbrel.

But not sure where to start from again. Is there seminars or something to get the inertia going?
