I just upgraded from 23.05x to 24.10 (compiled build). I followed the “In case the configuration wants to be preserved:” instructions from the Wiki and within minutes I was back up and running. Everything went perfectly smooth.
Thank you for keeping the Wiki up to date!! I was really dreading this update but this just made my weekend!
Edit:
I did deviate from the instructions by removing /etc/config/ubootenv and /etc/fw_env.config from a running 23.05 system. I then created a backup and proceeded to flash the ubi-installer. It was an unintentional mistake but harmless and prevents you from having to edit the backup. YMMV.
