You must use the following procedure to upgrade the switch software to Release 4.4 or the
upgrade will fail.
If you are using a release prior to Release 4.3, you must first upgrade to Release 4.2.4 before
proceeding with the upgrade to Release 4.4.
1. Backup the binary configuration file to a TFTP server.
2. Download the special image file (4.2.4).
3. Download the 1.0.0.15 diagnostic code file. The system reboots after this step.
4. Download the 4.4 image file. The system reboots after this step.
