Amazon Transform MGN (MGN) and Amazon Organizations
Amazon Transform MGN simplifies, expedites, and reduces the cost of migrating applications to Amazon. By integrating with Organizations, you can use the global view feature to manage large-scale migrations across multiple accounts. For more information see Setting up your Amazon Organizations in the MGN user guide.
Use the following information to help you integrate Amazon Transform MGN with Amazon Organizations.

This helps you to separate management of the organization from management of MGN. For more information see Setting up your Amazon Organizations in the MGN user guide.
