Ahh, it appears the functionality is there. Its just that the README
file hasnt been updated,
Theres now a transform-nifi command in addition to the transform-yml
command.

I had a look at the minifi toolkit.
However, it only appears to contain functionality for converting legacy
minifi config to minifi 2 config
Heres an excerpt from the minifi-tookit 2.1.0 README file
Valid commands include:
transform-yml: Transforms legacy MiNiFi flow config YAML into
MiNiFi flow config JSON
## Example
- You have an older version of MiNiFi located in
<legacy_minifi_directory>.
- You would like upgrade to the latest version of MiNiFi. You downloaded
and extracted the latest MiNiFi into <latest_minifi_directory>.
- Run the following command to migrate the flow and the bootstrap config
```
./config.sh transform-yml <legacy_minifi_directory>/conf/config.yml
<legacy_minifi_directory>/conf/bootstrap.conf
<latest_minifi_directory>/conf/flow.json.raw
<latest_minifi_directory>/conf/bootstrap.conf
```
Is there functionality somewhere to convert a nifi 2.x flow file to a
minifi 2 flow file,

Hi Robert,
Seems like the documentation has not been updated. I'm going to file
a JIRA
ticket to apply doc update about how we can import NiFi 2 exported flow
files into MiNiFi.
In a nutshell: before moving the json file into minifi, we should
convert
it with minifi toolkit. Related ticket for more details:
https://issues.apache.org/jira/browse/NIFI-12644
Regards,
Peter

Im having trouble getting code into minifi 2 from nifi 2.
The documentation here
https://github.com/apache/nifi/blob/main/minifi/minifi-docs/src/main/markdown/minifi-java-agent-quick-start.md
says
# Export the dataflow in JSON format.
# Move your new .json file to |minifi/conf|.
# Rename your .json file /flow.json.raw/.
Im using the option in nifi to "download flow definition"
However when I load that into minifi, I get an error message.
java.lang.Exception: Unable to load flow due to:
org.apache.nifi.controller.serialization.FlowSerializationException:
Could not parse flow as a VersionedDataflow
When I compare the file to the dummy flow file that ships with minifi.
The file that ships with minifi starts with
{
"encodingVersion": {
"majorVersion": 2,
"minorVersion": 0
},
But the export from nifi has
{"flowContents":{"identifier":"a2ac574c-635d-3df5-baf0-6cbf4dd5bdec",
So the 2 files dont appear to be the same format.
Is there some other method of exporting code from nifi that Im missing?
