The ROMMON needs to be upgraded.

A good working procedure about how to upgrade the ROMMON and the firmware can be found HERE.

Hope it helps.

I read the website provided above but I can't find information that I can upgrade directly from 03.04.04.SG to 03.11.04 same with rommon from 15.0(1r)SG2 to SG16. or maybe I just overlook it.

I'm aware of the upgrade procedure for 4500E chassis my concern is if there are intermediate ios version I need to take before I can upgrade to 03.11.04? Thanks

No you can upgrade to target version and make sure you upgrade ROM - that is what  @Leo Laohoo  thread suggesting
