Hello,

I am trying to migrate an older db version to a fresh install 8.1 umbraco, it has never been an issue before but this time it is bugging me.

I started out with umbraco 7.14, upgraded that to 7.15.6 without any issues, then i created a fresh 8.1 project and tried to upgrade the database and i got this issue:

The database failed to upgrade. ERROR: The database configuration failed with the following message: Nullable object must have a value. Please check log file for additional information (can be found in '/App_Data/Logs/')

Log:
