             Summary: Unannounced change to flow.json.gz
                 Key: NIFI-10016
                 URL: https://issues.apache.org/jira/browse/NIFI-10016
             Project: Apache NiFi
          Issue Type: Bug
          Components: Configuration, Core Framework
    Affects Versions: 1.16.1, 1.16.0
            Reporter: Daniel Salwerowicz
         Attachments: 2022-05-11--12-35-22.png, 2022-05-11--12-37-29.png

As far as I am aware there is no information anywhere that flow.xml.gz is now being replaced by flow.json.gz.
While it might not be that big of a deal to some I was very concerned that neither changelog, nor migration guide from 1.15 to 1.16 mention that this has occurred.
The only way I noticed that was because during update I needed to look up something in nifi.properties file and noticed a configuration option for flow.json.gz.
This lead me to search for what it is, when the change happened etc.
The only place in documentation where I can see flow.json.gz being mentioned is in the Admin Guide, which itself pulled a move comparable to ministry of truth from 1984 and just acts like flow.json.gz was always used in NiFi, no mention about change or what to do with old flow.xml.gz files.

I think that both changelog and migration guide should at the very least mention that switch to flow.json.gz has occured, why it happened, and how to deal with old flow.xml.gz when upgrading.

If I am wrong and there is mention of flow.json.gz anywhere in the official channels, then I apologize, and ask for link to them so I can read more.
It was very surprising to come across it when I wasn't expecting it after reading both changelog and migration guide.
