What is the best practice strategy for Managing Cisco IOS.
whether we need to upgrade every device for the latest release ?
Our current strategy is as follows
1) There is a security advisory released for your image
2) there is a bug / crash observed for your current image and the features which you are using
3) when a new feature set is required
