Data Migration from CRM 2013 to Dynamics 365 using SSIS

Hello,

I am migrating Data from CRM 2013 to Dynamics CRM 365 using Kingswaysoft SSIS.

Issue 1: While migration Lead information, Destination CRM Editor does not automatically map "CreatedOn" field. Nor I am getting an option to map this field from source to destination. I already have CreatedOn field in Dynamics 365 under Leads. What can be the possible reason?

Issue 2: Is there any way where I can migrate the Lead information along with the status? I tried migrating some leads. They all get the status "New" assigned to them. Can I migrate the leads which are "Qualified" or I need to migrate them as New and then qualify it manually? (I map statecode and statuscode from source to destination)

Thank you.
