Upgrading from wiki lite plugin to paid version via dashboard?

We were using the free version of the wiki plugin (lite).
I just purchased a membership and installed the wpmu dev dashboard and when I go to plugins it doesn't seem to recognize that I already have the wiki-lite plugin installed (meaning it just says "install" where I'd expect to see something like "upgrade").

What is the proper order of events here so I can upgrade the previously installed wiki plugin lite (that was not installed via the wpmu dev dashboard) to the one provided through the new dashboard plugin without destroying all of the content, etc from the wiki pages we have setup with the lite version?

How do I "upgrade" from lite to paid?
