This topic describes how to track incremental data by performing data comparison.
Background information
If the data or schemas of your source database have undergone major changes, you can
perform data comparison to track the changes. This feature facilitates the migration
of changed data definition language (DDL) statements.
Procedure
- Click the Compare Increments (Optional) tab.
- Click Start to perform data comparison and track the incremental data.
- After data comparison is completed, click Incremental Data Comparison History to view the records.
Note If you discover schema changes after data comparison, you can return to the previous
step and click
Start to synchronize schemas. For more information, see
Migrate schemas.
