When I first installed Linux, I didn't realize how different the root system would operate in comparison to a Windows PC. I bought a small extra SSD for my PC, 256 GB, not knowing that really a lot of things have to be on the same drive as my root. So now I have my root drive and a 2 TB NvME that has all my Steam games on it.
Today, I tried to setup Lutris because I wanted to play some non-Steam games but had to realize that those only properly run on the drive Lutris is installed on. Now, I am wondering if it is possible to migrate my OS, including all the data I have on my root drive, to the 2 TB drive. It wouldn't be too bad to lose the data on the NvME but I'd prefer if I didn't have to re download ~1,5 TB of games.
So would it be possible and, if it is, how would I do it?
