The implementation of global scope ACIs requires all ACIs specific to the rootDSE to have a targetscope field, with a value of base (targetscope=”base”). ACIs held in the rootDSE are specific to each Directory Server instance and are not replicated. Therefore there should be no incompatibility problems when running a Directory Server 6.1 server in a topology containing servers of previous versions. For more information about the changes made with regard to ACI scope, see Changes to ACIs.
In addition to the ACI change, the following attributes under cn=config must be migrated:
