I just recently installed Windows Subsystem for Linux 2. My only current Distro is Ubuntu and I'm using it for everything I do. I know that WSL 1 is better to handle projects that interact with both Windows and Linux, while WSL 2 is better for projects specific to Linux only.
I might want to switch between the versions depending on what I'm working on, and I would like to if it's safe to continuously change between versions?
Another alternative I found was doing something like:
wsl --export Ubuntu ubuntu.tar
wsl --import Ubuntu2 ./Ubuntu2 ubuntu.tar
and then setting the version of the second one with wsl --set-version Ubuntu2 2.
