Upgrade Failing

I have a 5508 WLC.  It came with Code 6.0.  I am trying to upgrade to 7.4.100.  No matter what I use, tftp or ftp, the download stops at 97MB.  The file is 116MB.  Is there something I am missing?  Do I need to delete something in flash to upgrade to this image?

you need to upgrade to 7.0 first, then step up to 7.4 - depending on the access points in your enviroment you may want to stay away from 7.4

Thanks.  I will try that.  I am using the 1042 access points, so I will stay with the 7.4.
