What exactly is exported depends on the Purpose of export setting. This is the first setting in the Export window. There are two options:
Archival or helpdesk exports everything, including authorization.
Transfer to another system exports the current, accepted, and published revisions and everything they need (DID, includes) without exporting the ITP/MDK Repository specific data (authorization). Labels, Characteristics, and older revisions can be exported as additional options.
The setting Export alias, which can be set on the General tab of the project configuration dialog, allows you to change the project name during export. This setting is only exported when using the option "Archival or helpdesk".
