Upgrade from 2.30 to 2.38: Issues and Resolution Plan

I have successfully completed the incremental upgrade process from DHIS 2.30 to 2.38 (which includes upgrades from 2.31, 2.32, 2.33, 2.34, 2.35, 2.36, 2.37, and 2.38). I have identified several issues that need to be resolved and have come up with a plan to address them one by one. Data Administration > Analytics tables management Generate Resource Table Issue: I have encountered an error while running the Generate Resource Table. Please find attached the error screenshot and the catalina.log…

1. Initial Cleanup:

• Remove unnecessary logs and error logs.
• Drop materialized views and clear analytics data.

2. Database Preparation:

• Keep only essential datasets, metadata, and transactional data. Exclude logs or deleted data.

3. Incremental Upgrades (Version-by-version).
4. Post-Upgrade:

• Regenerate materialized views and analytics tables.
• Test accuracy in programs, reports, and dashboards.

5. Testing and Verification:

• Run test scripts and verify key modules.
• Check compatibility of custom apps, APIs, and integrations.

Another potential solution is to install a fresh DHIS2 latest instance instance and manually import the metadata and data, if feasible. However, without knowing the size of your data, I can’t fully recommend this approach.
