Hello everyone,

we are trying to migrate from dynamics crm on-premise 8.2 to 9.1, but we are encountering an error.

The error seems related to security roles, specifically to our System adapter (Systemanpasser for us) which result already existing in the new environment.

After searching in our database, specifically in dbo.RoleBase table, we found out that the role Systemanpasser appears twice for every BusinessUnitId. We think this might be the problem. Weird is also, that some of the doubled Systemanpasser rows have NULL value in the /CreatedBy/ field.

Unfortunately the environment was created long time ago and I started only recently to work on this and don't know my way around too well.

Am I looking at the right thing here, in dbo.RoleBase? What could cause double entries in our database?

here´s a snippet of our DB result
