If you use the PC for testing then I would get that all setup first, to mirror your old setup from the Android TV as much as possible in Kodi 19.

When you have the PC working how you want, update the Android TV and then copy over the settings.xml for Xonfluence as part of updating everything.

Depending on which addons you use there may be significant behind the scenes changes related to python 3. It may be easier to setup from scratch than to try and fix the mess. A clean install means no leftovers to cause unknown problems.

Testing, but only very narrow, specific things.  It's more like a out of the box sandbox than a pre-production environment.  It's not anywhere near set up, and I'm not sure I want to do that.  Unless I could copy the setup of everything- Kodi, addons, settings, etc. over to AndroidTV wholesale.  Otherwise it sounds like yet another device to go through and set up, and one that I use only once in a blue moon. 

I was able to easily copy over the xonfluence folder and settings to a 'backup location'. 

Thanks for the suggestion, it is something to think about.  I am was having to bring my media drive over to my desktop to sort out tons of library problems. 

Wait-  I suppose I could do THAT.  I think my PC is on 19.  I'd have to check actually.  But I could bring my xonfluence settings over here, load xonfluence onto the PC and check to see if the settings file works.  That way at least I'd know what I'm in for.  And if it works then I'm a 1/3 of the way to setting up my PC as a full install.   Would make setting up the background menus, the tiles and shelf stuff easier, also. 

Hm. Something to think about- thanks for the tip!
