As you are aware we have been using the DHIS1.4 in Liberia since 2008
and we migrated to DHIS2 in February 2011. Since than we have been
using the DHIS2. Some questions have been posed to me and I have
decided to seek your technical assistant.
1. Can the DHIS1.4 data be imported into the DHIS2?
2. Can data elements in the DHIS1.4 be match with the new Data
elements in DHIS2
ex. In DHIS1.4 we have data elements called
Antenatal 1st visit 1st trimester under 18 years
Antenatal 1st visit 1st trimester 18 years and older
Antenatal 1st visit 2nd trimester under 18 years
Antenatal 1st visit 2nd trimester 18 years and older
Antenatal 1st visit 3rd trimester under 18 years
Antenatal 1st visit 3rd trimester 18 years and older
And in the DHIS2 we just have ANC 1st visit.
Is it possible to have those data in those data elements imported into
this so that we just continue the trend?

DHIS 1.4 does not have the concept of data element categories. So if
your DHIS2 database has been created with multi-dimensional data
elements, there is no easy way to import the data (at least easily).
It would have to be transformed prior to import. If your data elements
match exactly in name, then it is possible, but there are a number of
"gotchas" and caveats which are not documented, but start with
resolving all data integrity violations in the 1.4 database.
After having dealt with this for several years in Zambia, if there is
anyway to use one system or the other (but not both) it will make your
life much easier. Importing the data from 1.4 is fairly
straightforward if you do a conversion, meaning from 1.4 to 2.0 and
then you stop using 1.4. But as I said before, your metadata must
match exactly in the 1.4 and 2.0 databases, otherwise, it is much more
complicated and there is no automated way to do this. If you just
want to import the historical data, I would advise you to transform it
to SQL and do a direct injection into the database. Transformation to
DXF is possible, but considerably more difficult.
