BEFORE YOU START
When a cloudSwXtch has been updated, the connected xNICs and swxtchBridges must be manually updated as well.
In this article, users will be able to use the appropriate script to upgrade their xNIC.
Upgrading Linux xNIC
24/7 Operations
If the services need to be up and running 24/7, swXtch.io suggests that redundant systems exist, which will be referred to as "Main" and "Backup". During an upgrade, the Backup system should be upgraded, then the traffic should be routed to the Backup while the Main is upgraded.
There is no special procedure to upgrade an xNIC. The new version must be installed over the old one, as the installation script will handle the procedure, first uninstalling the old version, then installing the new one.
Please see Install xNIC on Linux, as the commands to initially install and upgrade are the same.
