Migrating Data via SSIS kingwaysoft to Dynamics 365 online

Hi,

i'm migrating CRM 2016 on-premise data to D365 online via Kingswaysoft component, i have noticed when i migrated all on-premise solutions to online, few fields have different schema and name value(mostly CASE sensitive like ps_adult,ps_Adult).

so when i migrate data via kingswaysoft it maps by name(but schema name is different) then run time throws error as 

'contact' entity doesn't contain attribute with Name = 'ps_adult' and NameMapping = 'Logical'

but the field is there with name is "ps_adult" and schema name is "ps_Adult"

is there anything we could change in the kingswaysoft component to make it work?, i cant update in the CRM solution as i can see this issue for almost 50 custom fields and have used in lot of forms, workflows, view so recreating these fields not possible.

could someone please suggest me the best way?

thanks
