I have a ton of companies in dynamics CRM that have old primary contacts associated with them, however I have a list of those companies that have new primary contacts now.
How can I import that new list into dynamics CRM to update those primary contacts for companies that already exists?
The data import wizard does not allow imports to update lookup fields so I can't use that to import updates for the primary contacts field.
How can I import updates for any lookup field that can't be done using the import data wizard?
