Transferring live data from one app to another

Hey guys,

I’ve just re-designed my app as a new project in Bubble. I didn’t change the data or data types at all as I wanted to make sure it was easy to transfer over.

I’m just having some issues transferring the data now because of composite data. A lot of my data is transferred between data types. For example, I have User and Books, and the User will store Books (with its unique ID) in their database.

The issue I’m facing is that I need to upload one data type first, but because they are intertwined with each other, there isn’t really “one” that I can start with.

Has anyone ever had this issue before and know of a good way to solve it?
