Tool !link! | Multicast Upgrade

Perhaps the biggest cost is time. A Unicast upgrade is inherently serial or limited by the server’s concurrent session limits. If a server can only handle 50 upgrades at once, the administrator is facing a queuing problem. If each upgrade cycle (transfer, verification, reboot) takes 10 minutes, upgrading 1,000 devices in batches of 50 results in a total operational window of nearly 3.5 hours—and that assumes zero failures.
