Migrate dual stack to ABAP only

[Former Member]

We have a dual-stack NW700.

We only want to export its ABAP portion and then use the export to build a new NW700 ABAP only.

1) is this feasible (i.e. the traget system will run? It's OK run without JAVA functionality as long as it runs)

2) if so, on sapinst , should select "system copy-> oracle->central system->system based on ABAP"

OR

"system copy-> oracle->central system->system based on ABAP + JAVA" ?

Thanks!

Hi Jessica,

You don't have to export the database.. Removing the java schema from the database is sufficient.

The installation guide explains how to remove a java add-in from a dual stack system.

Basically you do a drop user cascade from the java schema, remove the java software and delete the java specific parameters from the instance profile.

Kind regards,

Thanks!

The concern around your way is that:

1) The source is a PROD, so we cannot do it;

2) if do in your way after copy, it will need extra time.

So is it possible to exclude at the export?

Thanks again.

Hi Jessica,

In case you don't use the java stack of this system, it is completely harmless to delete the java schema from the database. It is separated by an additional schema, so it will not interfere with the productive ABAP system.

In case you have doubts, you can always contact SAP for this matter..

Kind regards,

Mark
