Swapping out an old 2TB pcie 3 drive for a newer 2TB pcie 4 drive.
I was leaning towards using dd, after shrinking the partition on the source drive so it doesn’t also ‘copy’ all the empty space.
Have you done this recently? What was your method?
Or is there a CachyOS/kde tool I may be unaware of?
Pretty much this. I’d copy anything I want to keep onto a temporary drive, (cloud storage, a USB drive, second SSD, etc), then use it as an excuse to refresh my install. Then just copy everything from that temporary storage.
