Well you wrote "What is the best way to do this without causing conflicts?"

By that,  if you mean simple system conflicts, no, as bagginsbill already pointed out.

However, if you use the same runtime folder(s) with Poser Pro as you do with Poser 7, you could run into conflicts where it comes to saving out new figures and/or shaders/and scenes. In other words, you could accidentally overwrite some of your P7 content, and may not be able to use it in P7 any longer.

Personally, when it come to professional work, I don't take the chances and whenever I update to a new version of almost any program I copy my old content into a new directory and then use that for the new program.

So if you have the disk space, I'd recommend copying your entire P7 project runtime folder to another location and then point Poser pro to use the copy, not the original.
