A customer approached us today, willing to spend annual funds on "keeping their equipment up-to-date" - this equipment includes several Cisco switches and a couple ASA firewalls.
Broad topic, but I've never been concerned about "firmware" upgrades on Cisco gear - it's always been about the IOS revisions. Given that, I've run into several occasions where upgrading the main OS (especially for ASA firewalls) has produced more pain than expected.
How would you react to this request? I'm not sure I believe that a customer request to "keep everything current" (the latest of everything) is a good idea in the Cisco realm. Plus, is there really any reason to upgrade the firmware of the devices (as opposed to just the OS versions)?
Open discussion here, and thanks!
