VIPM is actually pretty clever. As you know, when you open LabVIEW code written in a previous version of LabVIEW, it will usually compile OK (though it might use "old" LabVIEW coding methods), but will be saved in the current version of LabVIEW. What VIPM does is have a Drop-Down where you specify the LabVIEW Version (it "knows" which versions you have installed, and you can choose which one you want to use for the Code -- if you want it for all your Versions, you need to install it for each Version). It then compiles the code and saves it within the appropriate user.lib folder for that Version).
If you use LabVIEW 2013 and have installed VIPM 2015, it should show you (in its LabVIEW Version Dropdown) your LabVIEW Versions (which should include 2013). Set the Dropdown to the correct Version, let VIPM find all the Packages available, and start installing the ones you want.
