During an update technique, an update for the software application is received from a provider of the software application. Then, update information is either received from the provider or is generated. This update information specifies an update relationship between the update and at least a previous version of the software application. Next, inventory information associated with a portable electronic device is accessed (such as whether the previous version of the software application is currently installed on the portable electronic device). In response to the accessed inventory information, an identifier associated with the update is dynamically generated, and the update and the dynamically generated identifier are provided to the portable electronic device. Using the dynamically generated identifier, an application management system or the operating system installed on the portable electronic device determines whether an update workflow is executed.
