If you upgrade your GroupWise system from GroupWise 2012 or GroupWise 8, you might have legacy GroupWise gateways that are no longer supported. The Legacy tool enables you to easily delete them from your GroupWise system.
In addition, after an upgrade, you might have software distribution directories that are no longer needed in GroupWise 18. The Legacy tool enables you to easily delete them. Starting in GroupWise 18, GroupWise client software is distributed to user workstations using Client Auto-Update. For more information, see Using Client Auto-Update to Distribute the GroupWise Client Software.
