Migrating delta data

Important

Carefully review the Restrictions after restoring the database on the staging server. If you performed any of those tasks, you are not ready to migrate delta data. 

Delta data refers to any data changes that occur on the production server during the upgrade of the staging server. You can migrate delta data by using the Delta Data Migration tool.

The following table lists the high-level steps for performing delta data migration (DDM).
