   I gave these scripts a test when updating Metron 0.7.1 (HDP 2.6) -> Metron HDP 3.1 support branch.  They worked well, though I only setup Metron 0.71 with a handful of tutorial/walkthroughs beforehand, so the updated fresh Metron install was similar in respects to the configuration I updated it to.  There could be edge cases not covered by a simple upgrade test (such as a larger version upgrade jump).  But it's definitely better having the scripts than not having them.  For any serious production upgrade I would recommend:
   1. Use the script to pull the configuration of the existing Metron install
   2. Using the script to pull the configuration down from a freshly installed Metron update, 
   2. Manually comparing / updating the differences in the pulled configuration files
   3. Using the script to push the updated configurations into the upgraded cluster that has the freshly installed Metron/Mpack on it.
