Install, License, and Upgrade Configuration
The OcNOS Installation Guide provides instructions for installing and licensing OcNOS. It includes the following steps:
• Download the OcNOS installation image.
• Download an OcNOS license.
• Install OcNOS:
• From an FTP, HTTP, or TFTP server
• From a USB stick
• Using Zero Touch Provisioning
• Set up a license
OcNOS supports both patch upgrades and full upgrades:
• A patch upgrade updates to a new OcNOS image with bug fixes but without kernel changes.
• A full upgrade updates to a new OcNOS ONIE image with bug fixes, including kernel changes.
The OcNOS Installation Guide also covers procedures for upgrading existing OcNOS installations by either:
• Installing a new OcNOS version over an existing OcNOS version saves the existing configuration files.
• Installing a fresh OcNOS version is destructive and removes existing configuration files, SSH keys, and trial licenses. Users must manually restore these items from backups as needed.
