Hi,
   Are there updated NiFi docs for upgrading NiFi's that have the new access controls?  eg. 1.3 -> 1.4 or 1.4 -> 1.6?  There looks like a couple more files that need to be moved over... users.xml, authorizations.xml.. I copied over the state folder (although I'm not sure if I had to)

   I'm looking here:  https://cwiki.apache.org/confluence/display/NIFI/Upgrading+NiFi

Thanks,
Ryan
