MATLAB: How to upgrade the models under Matlab/Simulink

MATLABprocessrelease 2009simulinkupgradeupgradeadvisor

Hello everyone,
I am looking how to upgrade my models from Matlab/Simulink working on release older than 2009a (like 2007b or R13, R14) to release between 2009 and 2016.
What is the process to do it properly? I have seen the function upgradeadvisor so maybe a process to use it?
Thank you for your answer! (:
