moving configuration

Hello,

The end of DVB-T here in Germany makes a hardware upgrade necessary.
My good old Raspberry Pi 2 is to be replaced by Odroid-C2.

Problem: I'd like to transfer as much as possible from the ond config (LibreELEC 7.0.2, KODI 15) to the new config (LibreELEC 7.9.8 alpha, KODI 16 beta).
How can I do that? Knowledge level is about 20 years Linux experience, capable working in a shell.

You can start by using the built-in backup/restore tool in the Settings Addon.

Meanwhile I did most of it by reconfiguring kodi.
But I'd like to transfer tvheadend / tv channels settings from old to new. Where in the file system are these settings buried?

I'll be watching this. I always lose any changes I make in channel editor somehow. I suspect it's in a database somewhere?

Maybe. As far as I see there are 2 points to care for:
tvheadend with all it's channel/services/whatever setup and the mapping within KODI. Not to forget the correct assignment of channel icons.

To someone knowing more about that: Please share you knowledge. Thanks.

add-on configuration stuff is in /storage/.kodi/userdata/addon_data/ .. and moving config is simply about moving files around the right places

Sure? All the configuration of muxes, channels, mappings, icons, pvr schedules are held in these few small files?

Thank you.
I copied everything from /storage/.kodi/userdata/addon_data/service.multimedia.tvheadend
to the new machine. Everthing made it's way, no lost of data.
