i have a Raspberry Pi 3 with Raspbian Lite (based on Deb11) and i need to upgrade to Raspbian Lite (based on Deb12), or the last version of Raspbian comparable with my Raspberry Pi 3 Model B+.
Just in case you didn't find the answer yet, or someone stumbles on this post: Unlike Debian, Raspberry Pi OS does not support in-place upgrades:
To update the operating system to a new major release on your Raspberry Pi, image a second SD card with the new release. Use a USB SD card reader or network storage to copy files and configuration from your current installation to the new SD card. Then, swap the new SD card into the slot on your Raspberry Pi, and boot.
