Abstract: Methods, systems, and computer-readable storage media for deploying upgrade packages during zero downtime upgrade of production systems include actions of receiving an upgrade package, the upgrade package defining one or more changes to be deployed to a system that has already undergone partial deployment during a zero downtime upgrade, and including one or more objects having respective object types, receiving a deployment configuration, the deployment configuration providing a plurality of lists of object types for respective constraints and, for each list of object types, specifying a deployment option for object types in the respective list of object types, determining a set of object types included in the upgrade package, the set of object types comprising one or more object types, and selectively permitting deployment of the upgrade package to execute the one or more changes based on the set of object types and the plurality of lists of object types.

Abstract: A zero downtime upgrade procedure is initiated that upgrades a first version of software executing on a source system comprising at least one source server to a second version of software executing on a target system comprising at least one target server. The source system initially starts operating in a read-write mode. Thereafter, concurrent with the operation of the source system, operation of the target system is initiated in a read-only mode. Operations of the source system are then ceased by ramping down activities of the source system. Upon cessation of operation of the source system, operation of the target system is initiated in a read-write mode.
