Thank you for your answer @mediabit. The answer in your link is five years old, the imageTracker is the objectTracker by now, but it might work.

However, as Vuforia Sales just informed me, there is no way to set up more than one cloud database per app. Do you know if it would work to set up fake apps and just use the corresponding database in my main app? Anyways, this would become very expensive for me as I need to structure my targets in 16 databases because I have hundreds of targets that just have slight changes so they might be mixed up. So in the end, I would need 17 Licenses for my app while I'm not even maxing out the reco limit on my first one. This is ridiculous... and it's a bit of a bad time to switch the engine :-/

Yes, substitute ObjectTracker when you find older mentions of ImageTracker.

Only one Cloud DB can be active in an app at a time. For similar looking targets which might be recognized as the same, the way to distinguish between them for Device DB and Cloud DB would be to separate them into their own DBs. For Device DBs, you can just create as multiple DBs as you need without additional cost. You may want to experiment first with Device DBs and see if the outcome is what you want before trying to set it up in Cloud DBs.

Hi @dm3d and all, I have a very similar question to what's been discussed in this thread.

As it's been mentioned before, using Cloud DBs one can only track one trackable at a time. However, for the application I'm currently developing I always need to track two trackables at a time. My question is: once the first trackable stored on the cloud DB has been detected, is it possible to make a copy of it in a device DB? This would allow me to do what I'm looking for.

Also, I would like to ask whether it's possible to test the cloud functionality without having to buy a license (exclusively for development, obviously not for commercial use). I basically need to make sure it's technically possible to do certain things with Vuforia. I'm using Vuforia for Unity.

Thanks a million in advance for your help!
