Here is how to upgrade your WebServer machine:

• First stop replicator, and close all SCADA related programs.
• Next go to Control Panel > Programs and Features (Add and Remove Programs if it is Windows Server 2003) and un-install Replicator, SSRDS, WebSurv and WebSurv Administrator Editor.  If you have Archiver and Archiver Web Service please uninstall them as well.
• Assuming that you have the latest version now known as SurvCentral, double click on the ScadaInstallToolkit file and then begin to install Replicator, SSRDS, WebSurv, WebSurv Administrator Editor, and Archiver if you use it.
