We upgraded from the older version of RM but it was straight forward. We did decide to put it on a separate PC after a while however, but it was easy to setup a new server. I'll be back in the shop tomorrow and can give a better description then but the documentation supplied in the CPS download should help you get started.
I don't believe it's different enough from the older version to not be able to get things going from currently available documentation. From memory, install everything included (CPS, RM, Device Programmer, etc), setup the server to run using the RM Server Utility, go into CPS and click on the Radio Management button. After a few seconds, it'll ask for the server details. If it's installed on the PC you're using, simply leave it as "localhost" with the default port. Once in there, the RM comes with 10 licenses that allows you to manage ten radios (more can be added with an EID that's free).
Add your radio by entering its serial number and ID. Most info is optional and you can either enter it or leave it blank. Go to the RM Device Monitor (separate application) and check its settings to make sure it's communicating with the RMS and check all of the boxes you intend to monitor for programming (USB + LAN/Wi-Fi, Over-the-air, etc.).
Go back to the RM in CPS. I don't believe you need an OTAP key for Wi-Fi so go ahead and try to schedule a read operation to see if you can pull in the template from your radio that is presumably on the same LAN as your RM/CPS computer.
Apologies if I've missed anything (someone please correct me as needed)! As much as I've worked with RM and OTAP, I'm still working on my proficiency.
