The results of a database comparison can be added to a migration collection, which you can then use to create the packages that must be migrated.
Before you can run a database comparison, the package definition must exist in the source environment and the target must be defined in the Migration Manager application.
You can run a database comparison at different times to help determine what content must be migrated and tested. You can specify any type of package definition for the database comparison.
The results of the database comparison indicate whether the records match or whether the records are in only the source database or the target database.
