Hi Jeffersson,
The current product packaging is a bit confusing. Cisco is rebranding all of their management solutions under the Cisco Prime umbrella. All of the Prime products have a common look and feel and leverage certain architectural approaches. So moving up from LMS 3.2 onto 4.x will put you into Cisco Prime territory.
Within the "Prime" products there are (among others) "Cisco Prime Infrastructure" (also known as PI - 1.2 is the current release) and "Cisco Prime LMS" (4.2.3 is current). Prime Infrastructure (1.0) started out at the successor to Cisco wireless-only management product (NCS) and had been adding features along the way to bring it up to feature parity with LMS for wired infrastructure. It's not quite there just yet (current comparison here) so existing LMS customers are usually advised to stick with the latest version of LMS for now.
Still with me? Good. So the extra twist is that LMS 4.2 is "included" with PI 1.2 licenses - see the guide link below. So if you want LMS 4.x, you actually order PI 1.2 with "Lifecycle" licenses according to the number of devices you are managing. (There are also "compliance" and "assurance" licenses adding those respective new features. Compliance is available as of LMS 4.2 in the CAAM component. Assurance is pretty much a PI 1.2-only feature.)
So, my recommendation to you would be to upgrade to PI 1.2 and install and use LMS 4.2 (patched to 4.2.3 and updated with all product packages). If you have a VMware setup, the soft apliance (ova file) deployment option is the easiest implementation,
You may find the following two links useful in explaining this from Cisco 's perspective:

Don't worry - this won't all be on the test.
