1. A method for migrating locally-managed identities to centrally-managed identities, the method comprising: providing with computer hardware including at least one computer processor at least one interface control that enables a user to create a migration project; providing at least one interface control that enables a user to identify locally-managed identities associated with locally-managed account groups; providing at least one interface control that enables a user to specify a migration of the locally-managed account groups to one or more centrally-managed account groups such that the migration of the locally-managed account groups migrates the locally-managed identities associated with the locally-managed account groups to the one or more centrally-managed account groups and preserves local group membership information and identity attributes about the locally-managed identities migrated to the one or more centrally-managed account groups; providing at least one interface control that enables a user to specify migration rules for the migration project; providing at least one interface control that enables a user to specify a migration schedule for the migration project; and executing the migration rules with the computer hardware including the at least one computer processor according to the migration schedule to automatically migrate the locally-managed identities associated with the locally-managed account groups to the one or more centrally-managed account groups in a manner that preserves the local group membership information of migrated locally-managed identities.
