Migrating from GroupWise
Migration Wizard for GroupWise
The Zimbra Migration Wizard for GroupWise runs as a trusted application which requires access to gwtapp.dll. You must ensure gwtapp.dll is in on the machine and in your path (%SYSTEMROOT%\System32 is reccommended). If the gwtapp.dll is not in the path you see the following error message when selecting users to import:
If you encounter this error and then download and configure your path, you must restart the wizard to pickup the changes.
You can download the gwtapp.dll from this location: http://www.advansyscorp.com/formativ_download_tapp.htm
