=============
I would think that  expansion of  Key/index fields would be the  best
payback for many  reasons of sequencing retrieval.  Now once you start
that consider the full  set of applications all files and the impact to
recreate the files.  All should be relatively well as long as your
selected tools handle all that  to minimize the error rate and
implementation rate. And this can be  either phased or  implenemted  during
the available  window
