Hi Santi,
You can transport the authorization components, roles and user master records between the SAP systems or between clients within an SAP system.
Please have a look at Transporting and Distributing Roles - Identity Management - SAP Library document for more information.
If you want to transport manually created profiles, then Transporting Manually-Created Profiles - Identity Management - SAP Library document would be helpful. For transporting manually created roles, check Transporting Manually-Created Authorizations - Identity Management - SAP Library document.
There are also some other useful documents in the library: Role Administration Functions - Identity Management - SAP Library.
