Development vs. Production

When in development of a complete new application (before first production deployment) it is highly likely that a PAAS interface will change between iterative deployments. In this case it is recommended that previous application versions be completely undeployed and removed from the development system in order to prevent any failed deployments due to interface changes. This will require any in-progress work items and process instances to be cancelled first. In this case there are no application upgrade considerations and therefore any changes could be made to the application interfaces.
