I want to install MATLAB 2012a on an iMac with MATLAB 2009a which uses X11. As the new MATLAB release do not use X11, should I remove the old version before installing the new one?

Thanks for asking. No, don't remove the old version before you install the new version. When you install the new version, the installer creates a separate installation directory, leaving the old version intact. Here is some more information on the topic:

You are right. Both the versions occupy enormous Space. I found no documentation so far which explains about the dependecies on each other. Speaking from my past experience with Mathworks Products, I guess its safe and Okay to uninstall the older release and install the new release.
However they say it's not necessary on their website.
