Upgrade using the Command Line Interface

Use the following procedure to upgrade the firmware from the command line interface (CLI).

For this procedure, you will need the information provided by the Adaptive support team in the ticket, including the Server IP, Username, Password, Port, and other relevant details.
The legacy eosupdate command is deprecated for upgrades to 4.5.0. Instead, restore your saved settings after following the instructions in flash-upgrade to EOS v4.5. See Upgrading to EOS 4.5.0.
Following the flashing of the ELFIQ device, interface names change from ethX to pX. It is necessary to update your configuration to reflect the new interface naming convention.

Before you begin, collect the following information:
