Hi, You don't have to worry about SAS Base. As the name implies, in any platform/infrastructure, you get the full power of what comes with it. You should always have the choice of continuing to use SAS Base, even if SAS Eg is available. As for switching to SAS server, the only thing to worry about is server bandwidth and proper server power to accommodate flawlessly the whole group. If the server is scalable (which is the norm these days), everything should be fine. Happy coding, /Y
