Upgrade Recommendations

The contents of the nifi.properties file are relatively stable but can change from version to version. It is always a good idea to review this file when upgrading and pay attention to any changes.

Consider configuring items below marked with an asterisk (*) in such a way that upgrading will be easier. For example, change the default directory configurations to locations outside the main root installation. In this way, these items can remain in their configured location through an upgrade, allowing NiFi to 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. See Upgrading NiFi for more details.
