The following topics are addressed here:
Two files are created after migration is complete or after you perform a test migration. By default, the files are named migration.log and migration.report. Use these files to review, refine, and troubleshoot your migration.
By default, the files are saved in the same location as the migration utility configuration file. You can specify a different file name and location using the MIGRATION_LOG_FILE parameter in the configuration file. For more information about this parameter, see MIGRATION_LOG_FILE in Configuration File Parameters.
The following topics are addressed here:
The migration utility log file contains details about objects that were migrated, rejected, or skipped, and error messages if any errors occurred.
The log file is organized in the following sections:
Log file header with migration mode, log file creation time, OWB and ODI details, full path to the log file, and configuration options.
Migration start time.
Detailed information about the migration status of each object (whether migration succeeded, was rejected, or skipped) and error messages if errors occurred. For more information about informational, warning, and error messages that you might encounter when you run the migration utility, see Message Reference.
Summary information organized by object type, including the path to each object.
Log file footer with total execution time and migration end time.

The migration utility exclusion report contains a summary of the objects migrated, and lists whether migration succeeded, was rejected, or skipped for each object.
The exclusion report is organized in the following sections:
Exclusion report header with migration mode, report creation time, OWB and ODI details, full path to the report file, and configuration options.
Migration start time.
Migration statistics including how many projects were migrated, and total number of objects migrated for each project.
Detailed migration status for each selected object (whether migration succeeded, was rejected, or skipped).
Exclusion report footer with total execution time and migration end time.

When migration is complete, perform the following steps in ODI to verify the mappings that were migrated from OWB:
Use ODI Studio to connect to the ODI environment. See Connecting to a Work Repository in the Administrator’s Guide for Oracle Data Integrator.
Navigate to Topology Navigator and review the data server settings. You may need to edit some of the information such as user names, passwords, or JDBC URLs depending on your environment. Test each connection to make sure that each migrated data server is correctly configured. See Setting Up a Topology in the Administrator’s Guide for Oracle Data Integrator.
Navigate to Designer Navigator and review the migrated models and datastores in the Models panel. See Creating and Using Data Models and Datastores in the Developer's Guide for Oracle Data Integrator.
Navigate to Designer Navigator and verify the migrated mappings in the Projects panel by running the mappings. See Creating and Using Mappings in the Developer's Guide for Oracle Data Integrator.
Note:
Using the Migration Utility to migrate OWB objects to ODI is one of the many phases of migration. Please refer to the roadmap of migration as described in Understanding the Migration Process chapter for follow-up phases after the migration utility is run. Also, please note in all circumstances, manual work to fix up migrated artifacts in ODI shall be expected.
