I want to upgrade the IOS of my Cisco 2821 from Version 12.4(11) to v 15.1 (XB), but I have CCME v 4.2 (0), is there any problem if I only upgrade the IOS and leave the CCME as it ?

CME is a part of the IOS. You cannot upgrade the IOS without upgrading CME.

Hope this helps.

CME is part of the IOS, so you can't upgrade the IOS seperately from CME.

That said, if this is a production environment you should proceed with caution and be prepared to roll back as you may find bugs, etc.

You should also look at release notes and make sure your phone firmware will still work or needs to be upgraded too.
