Hi Vunda

Can you share what you got so far and what you would like to do eventually?
Maybe data or metadata synchronization would be an option?
https://docs.dhis2.org/master/en/user/html/dhis2_user_manual
_en_full.html#dataAdmin_dataSync
https://docs.dhis2.org/master/en/user/html/dhis2_user_manual
_en_full.html#metadata_sync

I attached a very basic Python script that just adds "myChange" to all
names of dataElements that begin with "ANC" (on Demo server).

To run it, you need to install the library *requests* (it's a very good
library for making API calls but you can use built-in methods as well) with
pip:

1) Install pip: https://pip.pypa.io/en/stable/installing/
2) In a terminal: pip install requests
3) Change directories to the folder where you downloaded de-renamer.py with cd
/path/to/folder
4) Inspect the code and what it does
5) In the same terminal:  python de-renamer.py

Good luck! Let us know how it went.

David
