If I am thinking correctly, (and I may not be as I have been up for 2 days now) you can upgrade from Mint4 to Mint5, the same way that you would with Ubuntu, however this is not really recommended, as the process can be troublesome, and the resulting install can easily be corrupt do to the fact that the kernel, Xorg, (basically what tells you OS what drivers to use, and port pathways to your hardware), and hardware drivers, are all going to need to be updated, and/or, changed, ESPECIALLY if you use an ATI graphics card. But the system will still have all the current drivers, software, and settings from the older version, which may conflict with the newer versions.
To make a long story short, (too late), you are going to be much much better off doing a fresh clean install, just make sure to backup all your data first, and when doing the fresh install, if you have not yet created a separate "/home" partition, this would be a good time to do so. If you have created one, then your data should be safe, as you will only need to format the root, (or "/") partition, but make a backup of your data anyway, just in case.
