Migrating templates using flow definition JSON as input

Learn how to use the Cloudera Flow Management Migration Tool to extract and transform templates for compatibility with NiFi 2 using a flow.json file as input. NiFi 2 does not support templates, so this step is required to ensure compatibility with the target version.

Flow definition JSON files do not contain any templates so this step can be skipped. However, if you run the template migration command using a flow definition JSON file, it will produce the following output:
sourceVersion
└── activity_log.json

targetVersion
└── activity_log.json

The generated activity_log.json file will contain only minimal information, such as the start and end timestamps of the migration process. No actual templates will be listed, as they are not present in the input.
