I am excited to use the new migration tool to import old Invoices. However, when I import the invoices, nothing gets imported in the Contact Name lookup field -- it just stays blank and doesn't get associated with a Contact.
Am I right to understand that I would need to "migrate" all of my Contacts in order to make the lookup work? I have around 15k Contacts. I certainly do not want to duplicate all of these contacts. But importing Invoices that aren't connected to Contacts is not useful at all. Please advise.
