Upgrading NetVisor OS Software for Freedom Series Switches
The NetVisor Freedom series switch always comes pre-loaded with NetVisor OS software. However it is recommended to upgrade the NetVisor OS software to the latest release, which can be obtained from Pluribus Networks Cloud (PNC).
For a quick introduction on the services offered by Pluribus Networks Cloud (PNC), refer to the following links:

Warning: If you are upgrading from NetVisor OS version 3.0.4 or earlier to NetVisor OS version 5.x.x, 6.x.x, or 7.x.x, then, you must first upgrade to NetVisor OS version 3.1.1 before upgrading to a later release. The direct upgrade from version 3.0.4 or earlier to version 5.x.x/6.x.x/7.x.x is not supported.
