Microsoft.Crm.CrmException: Database having version 7.0.1.129 is not supported for upgraded Microsoft.Crm.CrmException: Database having version 7.0.1.129 is not supported for upgraded.

When upgrading from CRM 2013 to CRM 2015 you get an error: Microsoft.Crm.CrmException: Database having version 7.0.1.129 is not supported for upgraded.

Cause:

This is usually because there is already a database that exists with the same ID. You will need to delete that Organisation in CRM deployment manager before upgrading the new organisation from the same name.
