You can install an older version of ROS (I assume you want ROS Indigo) alongside Jade and Kinetic. Which version of ROS is active and used depends on which setup.bash file you source in your terminal. Most people have one sourced automatically in .bashrc
, but some people do not so they can choose which version of ROS to use manually.
So to change to an older version, you need to install the version you want to use, and you need to change the line in your shell init script to source that version (or remove the line and type it manually when you want to use ROS). You should also probably clean your workspace's build and devel directories, too.
If the older version you want to use is not available for your OS version, you might need to install it from source (see http://wiki.ros.org/indigo/Installati... ).
You are also free to remove your current versions of ROS and install an older one instead.
