The Import function allows you to import from the history into the Developer model. This function allows you to import any of the following:
The latest revision of an entire Business Segment or Model.
The revisions identified by a version label.
The latest revisions of branches identified by a branch label.
Any revision.
From the File menu, select Import to open the Import Wizard and the Import Settings page.
Note: If you want to use History Explorer to retrieve old revisions, you must maintain the original migration database and at least one workstation that has that level of software on it.
