CATOS to IOS conversion is not possible for 4k switch. SUPs like sup1,2 runs CATOS and sup2+ and above work on IOS but conversion from CATOS to Native IOS is not possible on 4k switch as it is done on cat6k switch.
If you have a cat4000 running CatOS that means you have a supI or SupII, these sups cannot be converted to IOS. The same is true if you would want to convert a SupII+ or above which runs IOS exclusively, they cannot be converted to CatOS. Cat4000 sups have entirely different hadrware architecture than Cat6K sups so they cannot be compared.
