Changing ROOT version in SWAN

It might be easy but I am NOT sure how to change default ROOT version in SWAN session?

. /cvmfs/

in script at start of the session give lot of errors


In SWAN, when you start a session you select a software stack (LCG release) which comes with a particular ROOT version. If you need to change the ROOT version, the easiest is to stop your current session and start another one with the LCG release which contains the ROOT version you want.
