Changing cluster name in BOXI 3

Hi,

I have a vanilla install of Business Objects XIR3 SP6 with webapps deployed to Tomcat. Only a single member in the cluster. 

I now want to change the cluster name. Are there any instructions anywhere on how to do this? I can see in the CCM under Configuration that there is a 'Change Cluster Name to' option. Are there any other steps which need to be completed (i.e. web app configuration files and redeployment)

Thanks

Paul
