What is cdd564UpgradeImage?
This object designates which of the router's two firmware storage slots will be overwritten the next time a firmware upgrade is performed, distinct from cdd564BootImage which controls what actually boots. Choosing oldest(0) is the safe default since it always targets the image with the older build date and preserves the currently-running one as a fallback, whereas explicitly forcing image1(1) or image2(2) risks overwriting the image you're currently booted from. Before pushing a new firmware file to the unit, an admin would confirm this is set to oldest(0) so that an older build in bulk #2 gets replaced while a newer working build in bulk #1 stays intact as a rollback path.
