From "Release Notes for Laserfiche 10.4.1"

"After installing Laserfiche Server 10.4.1, the Server will automatically update the version 8, 9, 10.0, 10.1, 10.2, or 10.3 database. This update process will happen the first time the Laserfiche Server attempts to load a repository. The update process happens behind the scenes, and does not require any user input. It is performed in-place, and does not create a new database. When the update is complete, your repository will be compatible with the Laserfiche 10.4 Server.

Note: With large databases, the automatic schema update may take some time. Be aware that your Laserfiche repository will be inaccessible during this process even though the Laserfiche Server service is running. Check the Windows Event Log to see when the process is complete."

OK, where is this logged?  I could not find it on either the application or the sql server.
