If you open a JET Library database created with an earlier version of Author-it, it will be converted to the latest version, and a backup will be created in the same folder as the library with "Backup of " prepended to the original filename.
The upgrade process may take a long time if your library is large; this is normal.
SQL Server: You must manually back up SQL libraries
JET libraries are automatically backed up during the upgrade, but SQL libraries are not!
Important: If you are using SQL Server, the library will not be backed up automatically. You are strongly advised to export the database to JET first, or follow your normal backup procedure prior to upgrading the library.
Run Library Compact after a library upgrade
We recommend that you compact your library after upgrading to free up significant space.
