Is there a way to exclude migrated invoices from dunning process

Summary:

Hi team,

We are performing new implementation and as a part of it, we are migrating the customers from legacy system to Fusion. As a part of it, there are large volume of customers who have past over due invoices.

We are using Strategies collections method to dun our customers and these customers were not dunned in Legacy system. We are using past over due invoices data point to score our customers. When we migrate open invoices and customers, based on the scoring there are high chances where hard letters would be sent to the customers. We need to avoid that and we are looking way to exclude migrated invoices from getting dunned.
