How can an administrator perform a software upgrade for the IPO system?

Using the IPO Manager's upgrade wizard is the correct approach for an administrator to perform a software upgrade for the IPO system. The upgrade wizard is a built-in feature that guides the administrator through the upgrade process, ensuring that all necessary steps are followed to effectively update the system. This tool simplifies the process by providing an intuitive interface, which helps to reduce the likelihood of errors during the upgrade, manages dependencies, and ensures that the system remains operational throughout the process.

The other choices do not provide a viable method for upgrading the IPO system. Downloading updates through a mobile app is not applicable, as the management and upgrade of the IPO system require a more robust tool specifically designed for this purpose. Contacting the support team for assistance may be added support in certain situations, but it does not directly facilitate the software upgrade. Resetting the entire system would generally revert the system to factory settings, which is not the intended action when upgrading software and would lead to data loss and system reconfiguration.
