Hi everybody,
At WHO we have been working on an application to synchronize metadata (and data) from one to one or multiple other DHIS2 instances containing similar or different metadata. You may want to try it out! It synchronizes subsets of metadata and allows to schedule synchronizations of any subsets at regular intervals and between two or more DHIS2 instances.
The latest release is described here in case it helps: MetaData Sync app 2.2.0 now available
