Description

It would be nice to be able to switch flow persistence providers without losing state.

 

Current documentation says that this is not possible:

"In order to switch the Persistence Provider to use, it is necessary to reset NiFi Registry."

 

I think we should be able to support this via a nifi-registry toolkit that reads from the old provider, writes to a new one.
