Hi Gerald,

The biggest challenge is to get all the data in one database when you have
all these local district databases on DHIS 2 versions which may or may not
be compatible in terms of data import/export.

Also note that a database will usually get corrupted when you downgrade the
DHIS version, e.g when going down from 2.12 to 2.10 to be able to import
data from a district with that version (just an example) .

So keep lots of database backups, basically one for each district and
relevant DHIS 2 version combination and work your way up to 2.13 with
import/export.

When you have all data in one place running 2.13 you can then put a copy of
that database at each local office. Or hopefully you are able to switch to
online use by now.

Pay special attention to the tomcat log at DHIS 2 startup when the startup
routines (automated db update scripts) are done. If you get errors there
then your upgrade is likely to have failed.

Good luck and keep using this list for questions that you might have.

Ola
