Summary of the answers I received about this topic, 3 people answered: #1 has upgraded one production router, and till now are happy with it. But he fears to make a general deployment of 12.0 throughout the network, because of 11.0/11.1 problemas with the first releases. #2 is regression testing 12.0, and haven't noticed anything wrong. #3 have not upgraded a production router.

Have anyone here upgraded a 7500 router from IOS 11.1CC to IOS 12.0 ?
If you upgraded, are you happy with it ? ( ) Yes, it supports all the features I was using in 11.1CC ( ) Yes, it supports new features that I'm using now or intend to use ( ) Yes, it supports all cards and/or port adapters ( )
If you upgraded and you are you unhappy with it, why ? ( ) Because it lacks support of features I need ( ) Because it lacks support of card and/or port adapter I have ( ) Because it makes CPU go 100% ( ) Because it doesn't work at all ( )
If you have not upgraded, why ? ( ) Have no support contract, costs money ( ) Cisco told me not to do so ( ) My Cisco representative told me not to do so ( ) 11.1CC works very well, why should I risk ( ) I've seen no reason to upgrade (till last week security notice) ( ) Downtime concerns ( )
