Jan 26, 2021 10:19:13 AM com.sap.security.core.migration.com_sap_security_migration.engine_data_mc [Thread[main,5,main]] Info: Error while migrating controller com.sap.security.core.migration.UMEServiceRFCDataController. CSN component - BC-JAS-SEC-UME . Reason: The RFC connection data in the source system are conflicting because they contain data for direct server connection (ASHOST/SYSNR) as well as for load balanced connection (MSGHOST/GROUP/R3NAME). This set of data cannot be migrated. If the source engine does not use ABAP connectivity any more, clear these properties. If the source engine still uses ABAP connectivity, choose one of the possible connection types (direct or load balanced) by clearing the other set of properties.
