How is the correct steps for the upgrade of the WLC4400 from a version 4.1 to 4.2 version?

I backup the configuration running in the version 4.1.

I download, and put the file of the Software 4.2 in the TFTP directory.

I start the transfer from the TFTP to WLC.

The copy was succesfull.

I restart the WLC and Save the config.

But, the WLC lost the configuration (running the version 4.2), I connect to the console port and this showed the Wizard to start the initial configuration :S

What is the correct steps to upgrade WLC.
