>             Project: Apache NiFi
>          Issue Type: Improvement
>          Components: Tools and Build
>            Reporter: Koji Kawamura
>            Assignee: Koji Kawamura
>            Priority: Major
> In NiFi Registry project, there is an improvement to add new 
> FlowPersistenceProvider which can utilize Git technology.
> We need to provide a tool to migrate existing Flow snapshots those are 
> persisted with the FileSystemFlowPersistenceProvider, so that users can 
> switch from that to new Git persistence provider, or vise versa.
> A possible approach is taking a providers.xml file and a URL of running NiFi 
> Registry with a FlowPersistenceProvider which is currently used, then extract 
> all Flow snapshots then persist those with the new PersistenceProvider. This 
> way, existing Flow snapshots can be extracted into the new 
> PersistenceProvider storage. After that, NiFi Registry can be configured to 
> use new provider with existing Flow snapshots.
