I was googling this and didn't turn up anything.
If you have 100 some odd Cisco routers and switches how do you push out new IOS releases? Certain not by manually logging into every device. The only thing I found was the Cisco Auto-Upgrade Manager, but that's only for ISRs.
Is the only way to deploy Cisco switch and router updates through scripts? I could script this, but before doing this I wanted to be sure that the only way to do this is with my own scripts.
edit: Just to be clear I'm not looking for a way to make the routers automatically update themselves just an automated way to push out IOS updates to the routers.
Edit: Just as an update Puppet Device Managemnet (with Foreman) works pretty well, but I may just go with SolarWinds NCM

What I see most often is the use of a tool like HP Network Automation (which does far more than merely push IOS updates to Cisco devices - it supports all kinds of network devices, does configuration management, can be used for audit compliance, etc).
You might also consider some of the Open Source products like Chef, Puppet, Ansible, CFengine, and others.
It may also be possible to use something like PSSH - but I don't know.
