Hi Gerald,

I upgraded a system recently from 2.10 to 2.22, and it went pretty well
actually. There are some things you need to look out for along the way,
particular changes in the model, like duplication in orgunit groups, unique
(or non-unique codes) etc. I found it useful to turn on the Postgresql
logging during the process as certain errors may only be clearly visible in
the logs of the database, and not always through DHIS2.

Most versions seem to be availble from

https://www.dhis2.org/download/releases/2.XX/dhis.war

where XX is the version which you need. Otherwise, you may need to build it
from source code.

I do agree with Knut, that attempting an export /import to something like
2.12 might be a good start,but this has lots of limitations, so a
step-by-step upgrade would be the best way.

Regards and good luck,
Jason
