For GWIA system requirements, see GroupWise 18 Installation Guide. The GWIA can optionally be installed as part of creating a new domain. For installation instructions, see GroupWise 18 Installation Guide. The GWIA can also be added to a domain after it has been created. For setup instructions, see Creating a New GWIA in the GroupWise Admin Console.
As your GroupWise system grows and evolves, you might need to modify your GWIA configuration to meet the changing needs of your system.
