While vRealize Code Stream can be enabled on the same virtual appliance as vRealize Automation in lab or evaluation environments, it is not a supported configuration for production systems, particularly when vRealize Automation is configured in High Availability (HA) mode.
vRealize Code Stream 2.x does not support HA configuration and, if enabled on a vRealize Automation system in HA mode, can leave the overall system in an unpredictable state.
