As the title states, The vuforia version is downgrading from 7.0.47 when i import the vuforia package (by going to GameObject > Vuforia > adding ARCamera).
To give some background, i'm upgrading an old project. However when i delete all vuforia items in the project, the version number returns back to 7.0.47 when the Vuforia Configuration file is regenerated. Then simply returns to 6.2.6 when the package is re-imported.
I'm using Unity 2017.3.1.f1, the https://library.vuforia.com/articles/Solution/How-To-Migrate-a-Unity-Project.html page is outdated and doesnt seem to include instructions for vuforia 7.
