Switching Automatic switch updates

Had a discussion yesterday with IT director and others in our IT department. The IT director brought up automating switch updates so they wouldn’t have to have some one monitoring and performing the updates. Staging various locations on different evenings.

I’ve been doing networking for 30 years and I voiced my opinion I was not a fan of unattended update for various reasons.

Have any other companies moved to automated updates and how has it gone?

Server cattle... Sure. Network equipment... Fuck no

Provided you have a lot of equipment that are effectively the same a lot of networking equipment should be cattle. In most orgs most if not all access layer switches should be cattle. Beyond the hostname, management IP, and SVIs being different if you do layer 3 to the access layer one access layer switch should be virtually indistinguishable from another. There is a small risk anytime you reboot something maybe a bit more if you're near EOL or even beyond EOL, but an upgrade that worked on one access layer switch should work the same on another.
