This question already has an answer here:
Ubuntu 18.04 final beta came out a few days back. Ubuntu 18.04 will be released soon and I have recently upgraded RAM on my computer. I previously had less RAM so I started using Xubuntu, but now I want to move back to Ubuntu (although it's no longer the same, with GNOME desktop and all).
What would be the best way to do it? I don't want to lose data and would like to keep the applications I have installed on my Xubuntu 16.04 system. So in summary: I want to know if there's a way to move from Xubuntu 16.04 to Ubuntu 18.04 (with the GNOME desktop, not Xubuntu 18.04) and if yes, how reliable it is. Or would I have to just clean install?
