Importing a new flow into NiFi Registry

This procedure shows you how to import a brand new flow or a new version of a flow into a Registry instance.

Create a new one or update the NiFi Registry CLI properties file that refers to the Registry of interest. Set your CLI session to refer to this NiFi Registry CLI properties file.
For instructions, see Steps 4-6 in Connecting to NiFi Registry with NiFi Toolkit CLI.
Create a new flow.
```
john.doe@john bin % ./cli.sh registry create-flow -b 699ac53c-7be7-4082-8711-f9fff823826c -fd "This is the flow description" -fn "This is the flow name"

b748827f-565f-4a69-8ce0-7218fcab35f4
```
where -b specifies the bucket ID in the Registry where you want to add the new flow, -fd specifies the description of the flow, and -fn specifies the name of the flow.

This generates a flow ID for an empty flow with an initial version of 0.
Import a flow definition to the Registry as version 1.
```
john.doe@john bin % ./cli.sh registry import-flow-version -f b748827f-565f-4a69-8ce0-7218fcab35f4 -i dh_export_test.json
1
```
where -f specifies the flow ID and -i specifies the name of the input file.

note
If a flow already exists in the Registry, and you want to import a new version of the flow into Registry, you just need to reference the existing flow ID in the import command and the Registry will increment it as the next version.
For example:
```
john.doe@john bin % ./cli.sh registry import-flow-version -f 7ce2fdaf9-bf81-43fa-846f-f38f6891be95 -i mytestflow.json
2
```
