Modify existing installation for GW Cluster

Does anyone know if it is possible to modify an existing installation of the GW Mobile Server which was pointing to a single physical host / GroupWise server to a clustered GroupWise environment? In the documentationfor an initial install there is a check box for installing into a cluster, but that obviously was not checked when the original installation occurred. Running the update apparently does not give this option either. Any ideas or suggestions are most appreciated.
