Important first step is make sure you make a snapshot of database and keep a copy of the original war file (in case you need to revert back to where you started).
You might also consider revamping your postgres by upgrading to postgres 9.5 (apparently significant performance gains according to Lars) and installing postgis according to instructions here http://dhis2.github.io/dhis2-docs/master/en/implementer/html/ch08s03.html#d0e832 if you want to use new clustering capability. But you can do this as a separate step to the general upgrade. On 12 July 2016 at 13:55, Knut Staring <[email protected]> wrote: > 3.
