Debian 8.x (Jessie) to 10.11 (Buster) upgrade for Kiwis using BeagleBone Green/Black
In a few minutes I'll post below PRELIMINARY upgrade instructions. Will just one, or a few, of you please try them and see how it goes? Make sure you are sufficiently backed up in case something goes wrong.
I think these instructions should work, but it is difficult for me to test all possible situations. Especially the many networking possibilities people use. It is vital that you read and understand the complete procedure before proceeding.
