The main purpose of this tree is to contain ‘ready-to-go’ coutnries countries with sub-national level 1 and 2, and related geo-data ready for produciton production - they just need to be moved to the main PSI tree “PSI Countries” hierarchy.
This tree is also used for limited just-before go-live testing. In general, we do not expect more than 1 or 2 events for a program, or 2 or 3 data points on a dataset. Ideally data should be deleted.
