I don't want to give you information that requires CCO login, sorry :)

But if you have a cisco device in service and a default service sla the cisco partner has to give you CCO access.

IF you have bought a new router or switch lately default sla is a must and last for 1 year.

ok! no problem.

My next question is,

suppose i dont have enough flash to save both old and new ios, then I will make a copy of old IOS (as a backup) and install new IOS, then how should i start installing backup when new ios installation is crashed.
