Data Migration of Activities using Kingswaysoft

Hi,

I am working on Data Migration from CRM 2016 On Premise to CRM 365 Online using Kingswaysoft.

Facing challenges in mapping fields for activities (Email, Phonecall, Letter...etc)

I looked at the kingswaysoft FAQ link https://www.kingswaysoft.com/products/ssis-integration-toolkit-for-microsoft-dynamics-365/faq

but not able to understand how to map party list fields like From, To, CC, BCC .

I don't see From, To, CC, BCC fields in the CRM Source table(email) to map to destination.

Kingswaysoft FAQ , mentioned about JSON format source, what it mean? Do I need to write script component in SSIS and read data from any fields?

Can someone help me, which fields in the email table corresponds to fields(From, To, CC, BCC) in the destination.

Thanks

Krishna
