The last step in an Retirement project is to confirm a retirement run. Internally, during a retirement, data is not directly retired from data source to data target. Instead a staging schema and interim (temporary) tables are used to ensure that retirement data and associated table structures are sufficiently validated during the application retirement.
The following steps are involved in the process:
Generate Candidates. Generates Interim tables based on Entities and constraints specified in the previous step.
Validate Destination. Validates table structure and Data in the Target repository to generate DML for modifying Table structure and/or adding Rows of data.
Copy to Destination. Copies data to Data Destination.
Purge Staging. Deletes Interim tables from staging schema.
After the retirement project completes successfully, you cannot edit or re-run the project.
