I am running into problem during service migration process between environments. Especially with LBG. My end point LBG number of members change depending up on environments. DataPower functions doesn't allow me to add LBG members dynamically using XML management interface when I migrate my service to upper environments. I am trying to eliminate manual updates through WebGUI. What is the best approach to address this situation ? We use Websphere end points and LBG has members of the JVMs node name and container port. Webserver is not an option here. Based on number of JVMs in each environments, LBG members will need to updated accordingly during migration process using script that use XML management interface.
