Moving install to different partition
(feddit.de)
Okay, so I want to do something stupid and I’d like the input of smarter people to make sure I don’t screw it up. This is what I’ve got:
p1: EFI partition, p2: Linux install, p3: /home partition, p4: other Linux install, p5: another Linux install. Long story.
I use the third install (on p5) exclusively now. I want to clean up the mess seen above by moving it to p2 (currently occupied by the first install), and removing p4 and p5. What I thought I’d do (on a live USB) is:
- Overwrite p2 with the data of p5. (probably with rsync?)
- Edit fstab on p2 to change the UUID of the root partition to the new one.
- Try to boot from p2
- If it works, remove p4 and p5
Would that work the way I want it to? Anything obvious I’m missing?
I think your idea is pretty much correct. One step that might be missing is updating your boot loader to boot into the correct partition, depending on your configuration.
