How best to move the 15.1? I have an available empty 128G usb stick if an intermediary device is needed.
Assuming you have enough space you could simply run
btrfs replace start old-partition new-partition /
and after it has finished reinstall bootloader on new device. I am not sure what happens when it is interrupted so you certainly are advised to make backup first and probably test it in VM.
Thanks for reply Andrei (and jdd). I won't have time, until next weekend at least, to get back to this project. After 'google-time' on the subject, this is starting to look like it is more complicated, and time-intensive too, both in planning and in actual transfer, than I had anticipated :(
Well, you need to move data from old to new partition, so you need at least as much time as required to read data from old partition and write it to new partition. What did you expect?
Well no, these are both nvme drives, one of them fast (the receiver), the other extremely fast (the source), and the transfer is over a pcie bus, so the movement of the data itself between physical drives is not at all overwhelming, but it will still require backups too, and downtime, and much learning and planning to make sure I know exactly what I should be doing (or not doing). I'm certainly no btrfs expert. What did I expect? Well, something as simple as transfering an ext4 root system would have been nice :) Thanks again for the assistance.
