OcNOS supports both patch upgrades and full upgrades:
A patch upgrade means upgrading to a new OcNOS image with bug fixes, but without kernel changes.
A full upgrade means upgrading to a new OcNOS ONIE image with bug fixes along with kernel changes.
The OcNOS Installation Guide also contains the procedures for upgrading an existing installation of OcNOS either by:
Installing a new OcNOS version over an existing OcNOS version, which saves the existing configuration files.
Installing a fresh version of OcNOS, which is destructive and removes existing configuration files, SSH keys, and trial licenses. You must manually restore such items from backups as needed.
