> Update class names when import older flow from registry

> Key: NIFI-13613
> URL: https://issues.apache.org/jira/browse/NIFI-13613
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 2.0.0-M3
> Environment: Ubuntu 22.04
> Open JDK 21
> NiFi Registry 2.0.0.M3
> Reporter: Night Gryphon
> Assignee: Bryan Bende
> Priority: Critical
>
> I'm trying to migrate from NiFi 1.23 to 2.0.0 using NiFi Registry.
> When i import flow to 2.0.0 i get some missing components due to package
> names changes for some components like JOLT.
> The issue/bug is having such flow prevent cluster nodes to restart/rejoin.
> Once node is shutdown or disconnected from cluster it can't come back as it
> can't sync flow with master node due to missing components and so node just
> shutdown. Furthermore at the master node i can not delete or fix the corrupt
> process group as some nodes are unavailable and can't rejoin cluster.
> So to recover i has to delete nodes from cluster, delete process group and
> than rebuild cluster.
> To fix this issue class names has to be checked at the flow import and
> replaced according to updates in 2.0.0.
> Also flow sync at join cluster has to somehow deal with missing components
> which are exist in master flow and actually can be displayed and manually
> fixed.
