How to tell which version of Vuforia is being used in Unity Project

I am trying to upgrade a project from Unity 5.x to Unity 2017 and its included version of Vuforia. The problem is I am not sure how to tell which version of Vuforia I was using in the old version. It used Text Reco, and the date of some of the scripts was created 2/16/17 but not sure whether that is enough to glean the version number or not. Unfortunately, I can't simply open the old project because when upgrading to Unity 2017 it overwrote the old version of Unity. I saw another thread that mentioned looking in the logs in Xcode when you run the app and will show the QCAR version number, but I couldn't find that in my logs.
