Adding Licences to a Access Gateway pair

This is the process used to add additional licences onto our pair of netscaler 9 appliances.

Use "winscp" to add the license file to both CAG devices. They need to go in /nsconfig/license

Reboot the secondary node, log into the gui and check System/Licenses and make sure the Maximum Access Gateway Users Allowed number has increased.
Click Manage Licenses and make sure the added license number is visible. If not add it, choosing local appliance as the source.

Go into Access Gateway/Global Settings> change authentication settings
Change the Maximum Number of Users setting to the number of total license from above. If you do not do this adding the license will not achieve anything.

Edit the properties the Virtual Servers used for CAG and again increment the maximum number
of users.

Perform a fail over, then do the same on the new secondary.
