As you plan how to update GroupWise WebAccess, you need to consider both the WebAccess Agent and the WebAccess components on the Web server.
The GroupWise 6.5 WebAccess Agent cannot access older (pre-6.5) domains and post offices. In addition, WebAccess Agents older than version 5.5 EP SP3 cannot access GroupWise 6.5 domains and post offices.
Therefore, to continue to provide WebAccess service to users while you are updating your system, you need to:
The GroupWise 6.5 WebAccess Agent can communicate with the GroupWise 5.5 or newer WebAccess applications/servlets (on the Web server). If you have GroupWise 5.5 or newer, you can update your WebAccess Agent independent of the WebAccess components on the Web server.
The GroupWise 6.5 WebAccess Agent cannot communicate with pre-5.5 Web server components. In this case, you need to update the WebAccess components on your Web server at the same time you update the WebAccess Agent.
