Hi,
I am trying to upgrade my Organisation (currently in CRM 2013 SP1) to CRM 2015 (via Import Org method) and getting the following error,
>Crm Exception: Message: Upgrade Organization with Id=8c05fa04-db9c-e211-8cce-005056833018 failed with Exception:
System.Exception: Error.ActionFailed Microsoft.Crm.Tools.Admin.UpgradeDatabaseAction ---> System.Data.SqlClient.SqlException: 'attribute_attributeid' is not a constraint.
Could not drop constraint.
Appreciate your comments/solutions ?
