Check Point Gaia: Upgrading Gaia To R77.10

Check Point has made Gaia easy to upgrade through the WebUI, although I personally am a fan of CLI when doing upgrades.  Simply go to the WebUI, login, then Maintenance --> Upgrade.  Then upload your file and then upgrade.  You see below that it will ask you to take a snapshot first.  I suggest you do that.  Then, it will ask you if you want to upgrade, which is the reason you are doing this.  Say yes to both.
Make sure you do a 'migrate export' and FTP it to your PC before you upgrade.

Reboot and you are done.
