Hi,

I've just upgraded 7.3.0 to 7.3.1 using Nuget and during the upgrade wizard I get the following error (Using SQL CE):

The database failed to upgrade. ERROR: The database configuration failed with the following message: A duplicate value cannot be inserted into a unique index. [ Table name = umbracoMigration,Constraint name = PK_umbracoMigration ]

I've checked the umbracoMigration and there is a single row:

id: 1, name: Umbraco, createDate: 21/10/2015, version:7.3.0

Has anyone had the same issue?

Here's the log file of the DB upgrade:
