3 Post Migration Steps for Oracle BI EE

 After completing the data migration for Oracle BI EE, manually migrate the configuration settings for catalog groups and other components such as security for WebLogic and Enterprise Manager, BI Server, and BI Presentation Services.

• Migrating Catalog Groups
  Catalog groups are a feature of Oracle BI EE that allows administrators to organize users and application roles for security administration purposes.
• Migrating Configuration of Oracle BI EE
  After migrating the data, manually migrate the configuration information from the 11g system to the 12c system, which includes WebLogic security, Enterprise Manager security, the managed BI configurations, BI logs, BI Server, and BI Presentation Server configuration settings.
• Configuring the Database to Use DataDirect Drivers
  You must configure the database to use the appropriate DataDirect drivers. If you are using a database that is already configured to use the DataDirect drivers, modify the database configuration's odbc.ini file to use the correct DataDirect drivers. 
• Configuring Usage Tracking
  The Oracle BI Server supports the collection of usage tracking data. When usage tracking is enabled, the BI Server collects usage tracking data for each query. The statistics are then written to a usage tracking log file or are inserted directly in to a database table. After you complete migrating and configuring the 12c system, you must enable usage tracking in the NQSConfig.INI file.
• Configuring the SQL Server
  After configuring the 12c system, you must configure the SQL Server settings in the odbc.ini file.
• Adding Roles and Permissions
  After migrating the data, you must add roles and permissions for BI Administrator, BI Author, and BI Consumer groups.
• Configuring MySQL for Oracle BI
  You must configure the MySQL database to use the DataDirect driver. If you are using a database that is already configured to use the DataDirect drivers, modify the database configuration's odbc.ini file to use the correct DataDirect drivers.
• Checking the BI JavaHost Configuration
  Make sure that the XMLP and the BI JavaHost settings match with the settings specified for the configuration of the 11g system.
• Enabling Clusters
  After migrating the data, you must manually enable the ClusterEnabled parameter in the ClusterConfig.xml file to turn on the cluster instances on the 12c system.
• Enabling Oracle Hardware Acceleration and Compatibility Mode
  Hardware acceleration affects the autocompletion of features such as dashboard prompts, trellis charts and microcharts, Summary Advisor functionality, and aggregate persistence for the TimesTen In-Memory database. Therefore, you must manually enable the bi:hw-acceleration flag in the 12c bi-config.xml file post migration. You must also enable the bi:compat-mode-11g flag, so that the state of the 11g system is preserved at run time.
• Setting Compatibility Framework for Oracle BI Server
  The compatibility framework allows the BI Server to add new features or bug fixes in Oracle BI 12c (12.2.1.1 and later) that are not compatible with the Oracle BI 11g releases while providing a flexible framework that enables the BI Server to operate in a compatibility mode with the earlier major release. Individual features and bug fixes can be enabled or disabled independently using compatibility flags. Alternatively, you can set all the compatibility flags to the default values using a single COMPATIBLE_RELEASE flag for the Oracle BI system to be compatible with the earlier release, which is 11.1.1.9. Add the COMPATIBLE_RELEASE parameter to the NQSConfig.INI file to ensure that the migrated 12c environment behaves as closely as possible to Oracle Business Intelligence 11g Release 1 (11.1.1.9) environment.
• Migrating the Fusion Middleware MapViewer Configuration
  Oracle Fusion Middleware Mapviewer (MapViewer) is a programmable tool for rendering maps using spatial data managed by Oracle Spatial and Graph or Oracle Locator (also referred to as Locator). MapViewer provides tools that hide the complexity of spatial data queries and cartographic rendering, while providing customizable options for more advanced users. These tools can be deployed in a platform-independent manner and are designed to integrate with map-rendering applications. After migrating the data, you must manually modify the 12c MapViewer configuration file to contain the same contents as the 11g file except the Logging section.
• Unchecking "Required for Authentication" Option in DYNAMIC_OLAP_LOGIN Initialization Block
  To avoid authentication issues post migration, you must uncheck the Required for Authentication option in the DYNAMIC_OLAP_LOGIN initialization block.
