 ==== Memberships, roles and role mappings
 One major breaking change in this new version is the replacement of *MANAGEMENT* and *PORTAL* scopes by *ENVIRONNMENT* and *ORGANIZATION* scopes. It's not just a renaming but a dispatch of permissions among these 2 news scopes. As a consequence, all existing memberships, roles, groups and Identity Providers role mappings should be updated.
 
-* Memberhips, roles and groups have to be updated with migration scripts <<mongodb, here>>
-* Role Mappings for Identity Providers stored in database will be updated with a specific upgrader. See <<upgrader, Upgrader>>

 ==== Identity providers
 Because of the evolution of the roles and their scope, role mappings in *Identity Providers* must be updated. To achieve this, a specific service has been created and will be launched at APIM startup. As this is not necessary to launch this service more than once, it can be disabled with some configuration.
