I currently have Ubuntu 10.10 installed and I would like to upgrade to 11.10 (i.e. upgrading by two versions).

There are a couple of issues:

Firstly, I have Matlab installed, and I can't install this myself (I need to get it done by
IT support, which can sometimes be quite difficult). So I'll need to keep Matlab installed across upgrades.

Secondly, I have custom drivers installed (the NVidia developer drivers for using CUDA) and I'm not sure if this is a problem. I don't mind reinstalling this however, as they are freely available.

I could click the "upgrade now" button in the update manager, but I will have to do this twice (10.10->11.04->11.10).

Is it possible to put in an Ubuntu 11.10 CD and upgrade my 10.10 install? Will this leave Matlab installed?

Reinstalling and copying over data might not be an option due to my need for Matlab (proprietary software, eh? :P).
