What is the best way to determine if a new IOS will fix any bugs that exist in the IOS that you are currently running? I've used Bug Toolkit in the past, but it only seems to tell me what bugs are prudent to that image. I'm needing to find out if an image I want to migrate to has addresses any potential bugs in an image I am currently running.
The reason for this is to make a more compelling argument to make the migration. We have a number of 7206VXRs and 3825 are are running early 12.4 and I want to move to 12.4(20T) or above to add a specific feature.
