If you have created custom lists or if you have added sightings in an earlier version of this software, it can be converted once you install version 4. Do NOT uninstall the earlier versions of this software before you have done this. The conversion process can also restore observers, Hall of Fame entries and notes.
After you install version 4 simply click the word File in the menu bar and then click Import from Previous Version. (If you do not see this choice, click Help in the Menu Bar and then click Check for Updates.)
Enter the path to your database information or click the binocular icon to search for your data. Once the path has been selected, click import. This import works for version 3.0, 3.1, 3.5 and 3.9. If you have an obsolete version such as v2.0 or v2.5, this import feature will not work. In that case, you will need to reenter your data by hand. In Windows, the file you are looking for is named database.mdb and in Mac computers the file is bd. See the web-based Knowledgebase for more information.
