I have a DHIS2 tracker app with existing data. I’m considering replacing one category column with a different one. I’m concerned about the potential impacts on trend analysis and data loss. What are my options?
Welcome back to the community!
The best option is to reproduce and test this on a testing environment rather than applying the changes directly, and then if the results are satisfactory you’ll have the choice to apply them on the production instance. If there are any issues that you face during that process, please feel free to share them here.
Thanks!
Please consider the approach proposed by Al-Gassim. I just wana share my experience. We did the below work in test environment and tested it. We succeeded and moved the work to production system.
- We had elements in which we just added one more category option.
- We had elements in which we replaced some category options. In this case, we re-adjusted the data into new category options from the backend by writing some SQL code.
I hope you find it useful.
Good Luck
