2955 IOS upgrade

I am trying to upgrade the IOS of a 2955 using Cisco Network Assistant 5.5.  I am replacing c2955-i6q4l2-mz.121-22.EA12.bin with c2955-i6k2l2q4-tar.121-22.EA13.tar.  I have done this before, but for some odd reason now the the upgrade keeps failing.  I'm not given any reason, just that the upgrade fails.  Does anyone know how to upgrade it from command line correctly or why the upgrade is failing.  Thanks for any assistance that can be given.

You can also use WinRAR to "uncompress" the .bin file.

Re: 2955 IOS upgrade

You are trying to upgrade your image, a bin file (c2955-i6q4l2-mz.121-22.EA12.bin) with a tar file image (c2955-i6k2l2q4-tar.121-22.EA13.tar). Under IOS, the upgrade process are different between the bin file and the tar file. I am not sure how it was handle in CNA, which I'd never used. You should download the the IOS 12.1(22)EA13 in a bin file format and try again.

Thank you.  We CNA wasn't telling me at first that there wasn't room on the flash to do the upgrade.  I had to delete the old IOS and it ran just fine.  I appreciate your help.
