Hi Roger,


That really depends on your requirement.  The next one higher would be IOS 15 if you have enough DRAM (256) and flash to support it.

Also do you really need to upgrade? because higher IOS does not always mean better.

Thanks


It's not really as simple as that. It depends on why you are looking to upgrade ie. new features you want, bugs in release you are using, you fancy a change etc...


So you need to research your own IOS in terms of features, bugs etc. Cisco have a couple of useful tools for this sort of thing -


Feature Navigator


Software Advisor

the reasoning is more towards fancy a change since the current IOS is fairly old.

not other reason than that.

It's not that old


Personally if it has all the features you need and no bugs that affect what you are running then i would recommend staying with the IOS you have.

12.4 is not really that old.  As I said, newer does not mean better specially if every thing is working fine and you don't need any new features
