To demonstrate the database migration process, this section uses this sample scenario. Suppose you need to determine the changes that have occurred in a checkout database versus what continues to exist in the production database. In this case, you can create a baseline of both databases and compare them. One report shows what has changed in the checkout database. The other report shows what it would take to apply those changes to the production database.
When migrating entire databases or a large number of objects, it is important to import data as described in About Importing.
