Can't upload configuration file

[emulator]

Hello..

One of our NetVaunta 3430 routers appears to be failing. I'm going to swap it out with a our replacement unit. However, I can't get the replacement unit to accept the failing unit's configuration. When I upload the configuration (via the web interface), the system immediately takes me to a firmware update screen. I accept the defaults and reboot the unit, but once it comes back up, the old configuration file is still in place.

Any ideas on this would be most helpful.

Here's an update with a new problem...

I consoled into the unit and issued the erase startup-config to wipe the configuration.

I was then able to send the configuration file via hyper-term over xmodem. Everything appears fine, except now, I can't log into the unit without going through bootstrap mode. I've tried going into bootstrap mode and resetting the passwords, but the changes don't save. I can't log into the unit with the new configuration.

Any assistance on this would be greatly appreciated.

I found the problem as to why I was unable to log in via the console after updating the config file. There was a console password set that I was unaware of. I used the bootstrap mode to reset this password, and all is good now.
