In in a nutshell, the 1st steps install the 12 WebLogic shell and then "lay down" the BIEE binaries and deploy them to the WebLogic shell.
You then apply your 11g export bundle to the WebLogic shell created in previous step. There is no need for another domain to be created And I'm not sure you can apply 11g export bundles multiple times to the same 12c WebLogic domain.
thank you for your response.
I just had a look into the PowerPoint presentation you mentioned:
I think I have to point out that I did a fresh OBIEE 12c install, so i didn't use the preinstalled SampleApp-virtual machine provided by Oracle.
Instead I set up a new Oracle Linux Server:
-installed OBIEE 12
-configured OBIEE 12c
When configuring OBIEE 12c I was presented the screen on page 14 of your PowerPoint Presentation where you have to choose whether you want to install 'Oracle sample application (SampleAppLite), use your own existing BI Application from Export bundle (.jar file) or use a clean slate (no predefined application)
First time, i Chose "Oracle Sample application"
So now i dont want to start from scratch and create a new Domain and new rcu schemes for testing Migration.
I'd like to reuse my existing domain. I know i would lose sample application data then, but that would'nt be a problem for me.
I hope this will clarify my question.
In that case, it sounds like you need to delete your WebLogic domain as I don't believe you can re-purpose an existing domain as you've described.
You'll probably have to create a new domain and then use the config.cmd tool to attach OBIEE to it.
If your lite app is working, ie OBIEE is not broken because you did something bad with the lite app, then you can go ahead with the migration.
You don't have to start from scratch, when you go and deploy your migrate 11g things it will replace everything related to the SampleApp lite you deployed first time (it will not merge them or anything).
There is a command line tool you will call that replace the Sample app lite by your migrated content.
So you don't have to install or configure things anymore.
