Studio Enterprise 6 SP2  resets repository location when applied as upgrade.  We need to be able to capture current Repository Location and restore the same when we deploy upgrade to existing SP1 workstation installs.

 The options file (mfdsacfg.dat) is a persistent store of such MFDS options as:
 
  - the ES instance configuration store ("the repository")
  - is user access restricted
  - other security options (SSL)
  - journalling options
  - ES instance monitoring options
  - Web and API client timeouts
  - startup options
  - process uid (UNIX)
  - etc. 

You can preserve the mfdsacfg.dat file prior to installing Studio Enterprise 6 SP2 as an upgrade. Stop MFDS following completion of the installation, restore the mfdsacfg.dat to its original location, and when  restarting MFDS, all the regions should be retained to the current repository location after the upgrade.
