Converting to a Single Server System
Although upgrading systems running multiple method servers in a non-clustered environment is supported, if the system you are upgrading is using a cluster configuration, the upgrade requires that the cluster be converted to a monolithic configuration with a single method server. After the upgrade, the cluster can be reconfigured.
