I need to migrate data from CRM 2011 to CRM 2015 for different entities. I am using scribe insight for this purpose. I am stuck with the the migration of different entities belonging to Activities like Appointment, Letter, Fax, etc. If its a normal lookup field i would have used something like
DBLOOKUP(S25,"CRM 2015","Lookup Entity name","Matching field","Primary key")
There is a field type named 'Party List' which is lookup to multiple entities. How do I map this? So that I can easily migrate data from 2011 to 2015?
