Hi Jason,

HISP India is also in the process of upgrading dhis from 2.7 to 2.23. are
there any upgrade scripts available for earlier versions (2.7 - 2.16) ?

and also the biggest challenge for us right now is that 2.7 instance run
with mysql db, we need to convert it to postgres somewhere in this process.
any suggestion is appreciated.

Thanks.
