in the above , nvme0n1 is all my arch-installation ( btrfs with subvolumes ), i want to move all that into sda as i may have to sell this laptop, sda is a ssd which i added to my laptop. I also have to preserve the data inside sda. 79 GB is being used in nvme and 86 GB in sda.
i am able to come up with the right term to search on the internet, also considering btrf ( subvolumes ) , i wanted to ask here first.
Please point out to me some guide from archwiki or some other you might now of.
Thank you.
