Windows Subsystem for Linux Distributions:
Ubuntu-18.04 (Default)
Ubuntu
I made the mistake of setting up everything in the Ubuntu-18.04 version, which is locked to that specific version and doesn't allow dist upgrades (Please prove me wrong). This includes shell customizations, symlinks etc.
I would however like to upgrade Ubuntu every once in a while. What I do not want to do is manually find all the configuration files and copy them to the new distribution.
The Ubuntu distribution is the one from the Windows store; fresh clean with no modifications.
How do I get my data from the old distribution into the fresh Ubuntu store distribution? Or is there a way to upgrade the locked Ubuntu-18.04 distribution (also from the Windows store)?
I know of wsl --export and wsl --import, but as far as I can tell these keep the distribution (with in this case the lack of upgrades) and just place a copy of that distribution into another folder. Which does not solve the dist upgrade problem.
I ended up using the free, legacy version of Aptik (I couldn't get the GTK version to launch). Even though it's no longer maintained, it's still working perfectly well, and only took me a single command to export everything and another single command to import everything again.
