Maybe if changes are really simple a tool can help? Tools are needed for 
such kind of refactoring can be done automatically.

For some old games I wrote a script converter cause we completely broke 
the syntax (from XML to Lua) with a version of our engine, we do that 
because news features of engine was requested for next games updates.
It can appear like a time wasting, but it was fun to do.
