AppGate has introduced a rebranded App to the App Store on iOS devices as of AppGate SDP v6.0 which is now called the AppGate SDP Client. As this is a new App, iOS devices which previously had the AppGate SDP App v5.x installed will need to install and configure this new App to take advantage of the new v6.x capabilities. This article provides details for administrators and end users to transition to this new App.
Note: The new client installation will not override the existing client installation. This is a brand new installation and users will have their old client in place during the transition. As with all new installations, users will be required to configure their SDP Client with desired profiles. Once users are able to verify a successful connection with the new client, they can delete their old client.
Visual Differences:
The OLD client is named AppGate SDP.
