Mixed-Version Deployments

Mixed-version deployments are grids that consist of GridServer Manager versions 7.1.0, 7.0.x, and 6.3.1. This is an allowed configuration, as a convenience for large Grids that cannot upgrade all Brokers at once. You must address the following issues when running mixed-version deployments:

•

The Directors must be upgraded first to the latest version of GridServer Manager 7.1.0.

•

All Brokers must be on the latest service pack and hotfix of the minor version.

•

You must disable client version checking for Engines, Drivers, and Brokers at Admin > System Admin > Manager Configuration > Admin.

•

Hard-partitioning of Engines is required. That is, Engines must not be allowed on all the three GridServer Manager versions 7.1.0, 7.0.x and 6.3.1 Brokers. This is done with the balancer configuration.

•

You must deploy all versions of the C++ Bridge Grid Libraries via the Primary Director. If you upgraded the Director, the older bridges might already be there, but if the Director is a new installation you must copy them from your old Managers. The Engines automatically choose the proper library based on the Broker version. Because both versions of the C++ Bridges are used, Grid Libraries must also be used on an older Broker if the code is native, rather than using the standard resource deployment.

Mixed-Version Driver Compatibility

GridServer Manager 7.1.0 has backward compatibility with GridServer Manager 7.0.x and 6.3.1 Drivers.
