If you are intending to import GroupWise users from Active Directory, and those users have dots in their names (for example, danita.zanre), you will have a problem. A dot is not an allowed GroupWise userid, and the import procedure through the new Administration Console will to allow for this.
Fear not! My friend Morris has created a little utility that can assist. You can download it here – AD-GWImport
Note that the Readme lists a Linux version, but it is not available yet for Linux – only for Windows!
As always, let us know if we can assist with your upgrade!
