Upgrade Jessie and keep ROS kinetic

edit

Hello,

I successfully install and use ROS Kinetic on Raspbian Jessie (Deb-8) normally for a while. Now I want to install some Debian packages from apt (libbluetooth-dev, pybluez, and raspberrypi-ui-mods) but Jessie seems to be obsolete. My plan is to upgrade to Stretch and then to Buster/Bullseye.

However, from http://wiki.ros.org/kinetic/Installat... it seems Jessie is EOL and the build farm is turned off. I do not know if it can normally run if I upgrade to these higher versions. Or should I start over again, download its latest version image and install ROS Kinetic from the source following this http://wiki.ros.org/ROSberryPi/Instal...

I am quite new to ROS. Thanks in advance.
