Where are the relations of parent and child organizations stored?

[Almadzar]

I want to export my organizations to copy them from one host to another. I dumped the groups folder (this is where the organizations are stored in the ckandb database) and imported it on my other host. However, only the organizations were imported but not the tree structure (all the organizations are top level now). This leads me to my question, where the hierarchy structure is stored, or what table to I have to export to get the organizations including the tree structure?

@Almadzar The parent organization -> child organization hierarchy is stored in the member table
