"Upgrade" Xbuntu 20.04.2 to Linux Lite 5.2

[HiTechHiTouch]

I like running LL on one of my machines so much that I want to update/upgrade/convert my two other Linux machines.

I particularity want the LL desktop, and I expect to loose XCFE and Gtk customization.

I want to preserve all the applications I've installed, SMB/networking, MythTV, GCC build environments, etc.

Any suggestions how to approach this?

It's too heavily customized with a lot of hand edited modifications. Not doable, sorry.
