To upgrade to AppleShare 3.0, you must first upgrade the system software to version 7.0 or later.
The AppleShare 3.0 installation process converts an AppleShare 2.0.1 Users and Groups file for 3.0 use. If System 7 file sharing was activated, the Users and Groups file is active, and the file will be used for the AppleShare 3.0 file. If both files are present, a dialog box prompts the administrator to choose which file to use.
