And would like you to be awarem that there are different UUID#s involved. One resides in th filesystem ext2/3/4 itself, and can be modified with tune2fs -U (while fs is at rest/unmounted)
The other one site inside GPT, but you can change that also ((s)gdisk is your friend). But all that is meaningless, if you dont find the other end of the equation (like fstab, or grub scripts) that reference the said UUID's. But step by step you will get there, just be prepared to reboot several times and work your way up the chain.
