You can use the New System utility to create a new GroupWise system.
The process for creating a new GroupWise system is similar to the process of creating your initial GroupWise system (see Installing a Basic GroupWise System
in the GroupWise 7 Installation Guide), except that you don’t install the software from the GroupWise CDs. Instead, during creation of the new system, you are asked to specify an existing software distribution directory to use in the new system. If you don’t want to share software distribution directories between systems, you should create a new distribution directory. For information about creating software distribution directories, see Section 4.9, Software Directory Management.
