Migration from 2.29 to 2.34 Fails: System property dhis2.home not set

Current environment
PostgreSQL 12
TomCat 9

Database was previously on Linux machine.

Everything goes well if I do fresh installation but not upgrade. I am getting errors below:

Can anyone help on this?

Hi @fraka!

Thanks for posting this issue. I am hoping our flyway expert @Ameen can assist you :slight_smile:


Thanks. Can you assist me to reach him? The issue is failing me.

Make sure you are upgrading from 2.29 through 2.30, 2.31, 2.32, 2.33 to 2.34 and not straight to 2.34 from 2.29.

Make sure you follow the online instructions including dropping SQL views as you go. For some reason on our system, I had to use psql or PGAdmin to manually list and drop views and materialized views - for some unexplained reason, there’s been one materilaized view on one box that prevents us from upgrading the DB at times.

Looking at your log, that System property dhis2.home not set is normal - at that point it looks for the envionment variable and sets it accordingly - in your case to c:\dhis2. The ‘dhis-google-auth.json’ does not exist message is OK if you’re not using dhis-google-auth. The monitoring metrics being disabled is OK if you haven’t set up monitoring… there’s definitely a DB upgrade issue, just not sure that I can tell from that log what it is.

Thanks @Edward_Robinson - your suggestion worked well for me. I did upgrade from 2.29 through 2.30, 2.31, 2.32, 2.33 to 2.34 and all went well.

Just as an FYI. From 2.30 onwards you can upgrade to any DHIS2 version directly. Example: From 2.30 directly to 2.34 or from 2.31 to 2.33 or from 2.30 to 2.35 etc.
But you have to upgrade until 2.30 sequentially. Flyway ensures that from 2.30, direct upgrading to higher versions is possible.

Hi @fraka

Could you help to provide detail instruction on how to migrate 2.30, 2.31, 2.32, 2.33 to 2.34.
