boot image 15.1.1 upgrade

In   our test environment I upgraded Sups 720 to Sups 2T. The Sups 2T came with IOS   15.0.1. Looking at to the latest IOS; I found IOS 15.5.1. I upgraded to this   version and things seem to be working OK. In the web site, there is also   image s2t54-boot-mz.SPA.151-1.SY.bin. Do I need to   upgrade the boot image as well? If so, how do I do this? I haven’t been able   to find information in Cisco’s web info.

Bootvar nor version commands show me which boot   image the supervisors 2T are running.

Thank you for any information.

Re: boot image 15.1.1 upgrade

Nope, don't need it. Example, if you want upgrade to 15.1.1sy1 that came out a few weeks ago, just download it to your flash, change boot statement and reload, that's it.
