This section is designed for those who are moving existing GroupWise® 6.5 users, post offices, and domains to Linux. If you have GroupWise 6.0 or 5.x, review Updating Your GroupWise 6.x System to Version 6.5 and Updating Your GroupWise 5.x System to Version 6.5 to acquaint yourself with the issues involved in updating from one version of GroupWise to another. Because GroupWise 6.5 for Linux is functionally equivalent to GroupWise 6.5 Support Pack 1, there are no update issues involved in moving to Linux if you are already running GroupWise 6.5.
