Hi Dave, Either persistence provider should work fine for your use case. The error message indicates that flow ID does not exist in that bucket. You can browse the available buckets and flows in the NiFi Registry UI (in the default view), where clicking on a flow will display details including the flow id and bucket id.
You can also get this information from the CLI using the 'nifi-registy list-buckets' and 'nifi-registy list-flows' commands. If you are using the correct ids and still getting this error, it means something is corrupted creating a mismatch between the flow persistence provider and the metadata persistence provider. I’ve never seen that happen before. My guess would be it could be caused due to a configuration error, a change from one provider to another without foiloowing the right steps, or manually modifying the persistence files outside of the NiFi Registry API/UI I hope this helps you get on the right track. Let me know if you need further assistance.

I tried the CLI and it worked up until I tried to export a flow from ‘Dev’, got this message: 2018-09-09 10:52:45,911 ERROR [NiFi Registry Web Server-19] o.a.n.r.web.mapper.ThrowableMapper An unexpected error has occurred: org.apache.nifi.registry.flow.FlowPersistenceException: Flow ID 0df59975-2683-4e84-91f5-f616bbed207a version 1 was not found in bucket CleverGit:34658e23-c138-4085-9280-6359f322672d..

Am I going about this the wrong way? Should I just be using the default flow persistence provider?

The recommended way to move flow snapshots across air-gapped environments at this time is and export/import with the NiFi CLI [1], a tool included the NiFi Toolkit, which you can download here [2]. The import step will create the necessary metadata for you. Let me know if you have any questions!

Try setting up a snapshot of that too.
