Dynamics CRM Errors when importing unmanaged solution

In this article we see Step by step How to fix Dynamics CRM Errors when importing unmanaged solution , in both CRM 2011 and CRM 2013 .
Several errors can be thrown by Microsoft Dynamics CRM while importing an unmanaged solution from test to production environments, such as "This import has failed because a different entity with the identical name" , or "Field Is Not Unique"...
Usually the causes are differences of schema between fields or entities.
