A tenancy administrator can create policies in Oracle Cloud Infrastructure Identity and Access Management (IAM) to grant permissions to groups on resources in compartments in a tenancy.

For example, you can create an Administrators group whose members can access all Database Migration resources. You can then create a separate group for everyone else who's involved with Database Migration, and create policies that restrict their access to Database Migration resources in different compartments.

For a complete list of Oracle Cloud Infrastructure policies, see policy reference.
