Thanks for the feedback.

The doc is in DRAFT mode and still being improved. We need to add this clarity in beginning that the 9.1.1 upgrade software is available under BE6000 category.

http://software.cisco.com/download/release.html?mdfid=284668396&flowid=37862&softwareid=282074295&release=9.1.1%28a%29&relind=AVAILABLE&rellifecycle=&reltype=latest

It will recognize the hardware (as BE5000) and offer the upgrade option.

Please let me know your experience with this document.

Thanks
