Upgrading from LogTen 2.x

Where’s My Data!?

First of all, don’t worry, LogTen Pro 3 & 4 do not touch LogTen 2.x data in any way. If you’ve upgraded to LogTen Pro 3.0 and you’re not seeing your data, chances are you were not running the latest version of LogTen (2.7.12) prior to updating.

LogTen Pro 3.0 automatically imports data from LogTen 2.7.12. If you did not have 2.7.12, you can download it here.

Just fire it up, make sure you have “All Flights” selected on the left, and then quit. Now launch LogTen Pro 4, and if you haven’t saved a document yet it will open an empty one and automatically import your data from LogTen 2.x. If you HAVE saved a document in LogTen Pro 3 or 4, then simply create a new logbook under the File menu and it should automatically import.

(If for any reason the import does not begin automatically, the file exported by LogTen 2.7.12 is located in your home folder at ~/Library/Application Support/LogTen/LogTenData.txt. You can open a new document in LogTen Pro 3 or 4 and select Import -> Flights under the File menu, then select this file and choose import.)

All this is necessary because LogTen Pro 3 and 4 use a new data architecture (Apple’s CoreData framework) to provide dramatic speed and reliability improvements, thus it cannot read the old data files. LogTen 2.7.12 exports a special file that LogTen Pro 3 and 4 can import.
