Update Vuforia Image Database

Hey there,
maybe it's a general question concerning the Unity Editor, but I want to update the Vuforia Image Database in Unity and replace an image target with a complete new one.

How do I update a database without messing everything up in the Asset-Folder?

 

If you re-import the database with updated targets the same way you initially imported it you should be able to update only the things that changed. If you're worried this might mess something up in your project, you can create a backup and give it a try that way first.
