During lead conversion, all the default lead fields (under Basic Information) are automatically mapped to the default fields of the newly converted contact, account and deals. There are a few fields that become irrelevant (such as Lead stages, Unqualified reason and Territory) when a lead is converted to a contact, so the data in those fields aren’t carried forward.
The table below helps you understand how the default lead fields are mapped during lead conversion.
|Default Lead Fields||Contact||Account||Deal|
|Work (Phone number)||✔|
|Company annual revenue||✔|
|Number of employees||✔|
|Deal Expected Close Date||✔|
