When comparing source between different Visual DataFlex versions it is a HUGE time saver to do this using source code compare tools.
Below is a few rules one can use to compare sources between VDF11.1 and VDF12.1
 
The tips below are for a product called Beyond Compare, but i'm sure your product will do fine too. If you are not using a product for this then GO BUY ONE! it is the best investment you can make EVER.
 
=== How-to set up Beyond Compare ===
In order to change the rules on how BC compares, you should go into compare source mode and then click on the "guy with the cap" in the toolbar
 
''' General Tab Page '''
Name : DataFlex
Associated with: .src;*.pkg;*.dg;*.vw;*.dd;*.sl;*.ddo;*.rv;*.tt?;*.wo;*.utl;*.nui
 
x Whitespace includes TABS and spaces
 
''' Importance Tab Page '''
Unimportant text group >> put a check in all of the checkboxes
This is also the place where you can add custom rules/filters
