BW Upgrade 7.0 to 7.4


We are upgrading BW from 7.0 to 7.4. We have carried out all pre-upgrade activities also.

But many of the data flows (master and transactional) are still in 3.x.

Migration of 3.x to 7.0 flows needs to done before or after upgrade? Which is recommended?

Is there any tool to do at mass level/ or any standard program or T-code? Migration of one by one will be tedious.

Please share your thoughts.

    Technically, you can migrate your dataflows either before or after the upgrade. This is not mandatory to do it before. As M Tibollo mention, it could be interesting to do it before (if you have time ;-).

    There is a migration tool that allows you to migrate a selection of update rules at once. See the following doc:

    BW 7.30: Data Flow Migration tool: Migrating 3.x flows to 7.3 flows and also the recovery to 3.X flow

    You begin by building a migration project (with all the update rules you want) and then execute the migration itself. Transformation and DTP are created ; process chains are adjusted etc.

    • there are lots of docs and how-to and step-by-step etc on the migration from 3.X to 7.X. When we did this migration we found all necessary info in the SAP provided documentation and additional OSS notes.

      you need to migrate one by one. It seems obvious you need to migrate before the upgrade. Else if you have an error afterwards, you can't be sure if it's linked to the migration or the upgrade.

      But really do have a look at the documentation provided by SAP.
