To make the upgrade process easier, it is advisable to change the default configurations to locations outside the main root installation directory. In this way, these items can remain in their configured location through an upgrade, and NiFi can find all the repositories and configuration files and pick up where it left off as soon as the old version is stopped and the new version is started. Furthermore, the administrator may reuse this _nifi.properties_ file and any other configuration files without having to re-configure them each time an upgrade takes place. As previously noted, it is important to check for any changes in the _nifi.properties_ file of the new version when upgrading and make sure they are reflected in the _nifi.properties_ file you use.
