Upgrading a Project that uses Distributed Servers

If you have implemented clustering in Version 6.x using Distributed Servers, a Global Include Project, and Cluster Projects, configure your project to use clustering in version 7.0.

The existing structure of the Global Display Project and Cluster Projects can remain the same (that is, the Global Display Project includes each of the Cluster Projects).

The following points describe a recommended project structure for clustering in version 7.0:

• Include a separate communications project in the Global Display Project. In this project, it is recommended that you define only the Network Addresses, Clusters, and Servers.

• Note: Defining a separate communications project means that when the Global Display Project compiles, it has the communications information without needing to load the data from the Cluster Projects.

• In each Cluster Project, specify the appropriate cluster for alarms, trends, reports, SPC tags, and accumulators.
• You may need to modify the buttons and pages in the Global Display Project, particularly if they are using Cluster functions which have been modified or deprecated.
