Unlike systems that reside in our campus datacenter, the Oracle Cloud system will be updated on a fixed schedule, largely set by Oracle. There are quarterly releases which may affect functionality and will be tested by the DASH team in a test system before they are applied to the production system. In addition, smaller patch updates may be released monthly. Though the DASH team will test as many scenarios as possible, just as with on-premise systems, it is likely that campus users will discover changes to the system after updates are applied.
