Really, I don't want to give you any heart attacks with this fact.

But the answer is yes. You will have to upgrade to the newest one. In other words it is not upgrade but the new fresh installation of RMS.

RMS installation instructions are located here http://www.boonex.com/trac/ray/wiki/RayServerInstall

The installation is not so compliacted. Of course, this requires some skills in using SSH and command line.

Please let me know if the instructions or part of them are not clear enough see more to you. We will extend them.
