Copy Data From One Workbook To Updated Workbook Using Macro

I am creating a spreadsheet to provide to a group of about 40 people. The spreadsheet allows each member to track the referrals they receive and give. I need to plan on creating updates for the spreadsheet and want to make it so they can easily transfer their data to the most current version in the future. Here is a breakdown of the workbook:

Worksheets:
Members
Lists
Referrals Given
Referrals Received
Totals
Formulas

I need to copy the data that they have input from the following worksheets:
Referrals Given
Referrals Received

Here is a breakdown of the "Referrals Received" worksheet:
A1:V4 - Data that will not change and includes many named cells
A5:Nxxx - Dynamic Named Range where they input their data
O5:Vxxx - Contains formulas

I need to be able to copy
A5:Vxxxxx
from the old workbook to the new

Some side items to note:
There is VBA in the worksheet of
Private Sub Worksheet_Change(ByVal Target As Range)
and included in the code is an Unprotect & Protect code to always keep the sheet protected

I figure whatever works for this sheet will work for all the sheets.
