I am afraid that I will lose my data if I convert a Deal to a Project. What should I do? What are the benefits of mapping the fields of a Deal to a Project? I can see a few fields that are already mapped by default. Why is that? Can I delete the fields that are mapped by default in the CRM? How do I add a mapping? Can I add any field from Deals as a part of field mapping? How do I modify a field mapping? How do I add a custom mapping? How do I modify a mapping?
