Hi,
I'm trying to upgrade OBIEE 12.2.1.2 to 12.2.1.4.
I have installed FM in new Milddleware/Oracle_Home.
I have installed new OBIEE in the same location.
Next step is to run Upgrade Assistant in readiness check mode.
You need to provide path to the older version and provide details about all used schemas (DB user name and password).
I have successfully provided details for WLS and OPSS schemas.
There is error for IAU schema.
As I have checked in Toad, I can login to DB using credentials for IAU user. There are several tables, but looks like all of them are empty.
Error which I'm receiving is:

Any suggestion how to solve this?
Difference for other schemas is that schema user was not entered by default and list is empty.
I can't skip this step. I know it's only Readiness Check, but I guess that in upgrade process it will also return error.
I have created SR, but for several days without answer from Oracle
Please send help!
