how to copy data between two DML forms APEX

I am using APEX 4.2.5



I have two different DML form with same design one for Creating new Record (Create Record form) and one for editing the data (update Record form).



If I update the design of "Create Record" form by including few more data points, same need to be redesigned for "update Record form". Is there any way where I copy the Fields from one form to another ?
