Goal

A WebLogic domain running with a dynamic cluster setup needs to be scaled up. The current configuration is as follows.

Host1 --> MS1:Port1 and MS3:Port3
Host2 --> MS2:Port2 and MS4:Port4

To achieve the desired scale up, the desire is to add the 5th and 6th managed servers on Host3 without impacting the existing Host1 and Host2 configurations.

However, when the additional managed servers are added to scale up the instance, the existing MS3 is automatically migrated from Host1 to Host3 and MS4 from Host2 to Host1 in round robin fashion. Is it possible to retain the existing configuration and force the new instances to be created on Host3 only?
