Our organization has grown larger since our current process was established, and like many during Covid, most of our staff has been required to work remotely whenever possible. An issue that has come up that I would like advice on is upgrading switch and router images in an automated/unattended way.
Our current policy is that you can stage an upgrade to install during a change window, but you will need to physically be present prior to business hours to verify its functionality. We also have a limited change window of a single day per week. My thoughts are with our small team, if we did one or two locations per change window, any image upgrade process will take almost a year.
We currently use all Cisco switches/routers, and have just started to experiment with DNAC (which was given for free)
How are you all handling upgrading images and verifying success? A bonus question: How often do you update your switch images?
