I finally got LTSC 21H2 installed, which allows me to use WSL2. I checked the box within Docker Desktop to use WSL2, which caused all containers and data to disappear. I reverted back to Hyper-V.
So, is there a sorta-easy method of migrating everything over to WSL2? Or, do I need to install AIO from scratch under WSL2 and restore from a backup?
