A challenging BI Server and BI Apps migration from Version 10.1.3.4 to the latest 11.1.1.7,
InformaticaandDAC that included redesigning the Security Model, RPD Migration, Catalog
Migration, tuning the Configuration files and upgrade validation.
Security model was redesigned to conform with 11g OPSS (Oracle Platform Security
Services) and implemented Role based security for content and SQLProvider for row level
security. Also, tuned to RPD / Business Model to conform with the best practices and
eliminate consistency checker warnings.
Used accel-BI, an automated upgrade validation tool that could run the reports from the
OBIEE Catalogin a batch mode before upgrade; takes a snapshot of the data and compares
the data again withthe same report post upgrade. It compares data and formatting as well
