Upgrade a Check Point Gateway with CPUSE, Step by Step
CPUSE (the Gaia Deployment Agent) is Check Point's built-in tool for importing, verifying, and installing hotfixes and major-version upgrades on a Gaia gateway. In this guide I use it to take one gateway from one major version to the next. A major-version install reboots the box and replaces the running OS image — while it runs, that gateway passes no traffic and its management is offline. Treat it as a full outage, not a quick patch.
