Before you migrate to Oracle Analytics Server, you must replicate the users and groups that Oracle Analytics Cloud uses in Oracle Analytics Server. The way you do this depends on whether you're using Oracle Identity Cloud Service or an embedded WebLogic LDAP server. If you subscribe to Oracle Analytics Cloud - Classic through Universal Credits, you manage users in Oracle Identity Cloud Service. If you subscribe to Oracle Analytics Cloud - Classic through a traditional metered or unmetered subscription, you might be using an embedded WebLogic LDAP server.
