Creating migration groups
You create a migration group to specify the configuration content that is to be migrated in a package. If you create your own object structures or reorganize the predefined object structures, you might need to create a migration group to contain those structures.
About this task
Be sure to identify all the relationships between the business objects, including dependencies. If you omit required migration objects or dependencies, packages that use the migration group might fail to deploy.
Include all the necessary migration objects so that you maintain the referential integrity of the database to which you are migrating the configuration content. Assign the correct process order numbers, to ensure that the migration objects are processed in the correct order. Use the predefined migration groups as a reference when you are adding dependencies to your own migration groups.
