             Summary: Incorrect Local Changes shown when upgrading from 1.18.0 to 1.19.1
                 Key: NIFI-11001
                 URL: https://issues.apache.org/jira/browse/NIFI-11001
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.19.1
            Reporter: Bryan Bende
         Attachments: Parent-from-1.18.0.json, Screen Shot 2022-12-21 at 4.27.47 PM.png

Scenario to reproduce...

Using 1.18.0, do the following:
 * Create a PG named Parent
 * Inside Parent, create a PG named Child
 * Inside Child add GenerateFlowFile connected to UpdateAttribute
 * Start version control on Parent
 * Export Child without services
 * Import the exported Child inside Parent, so there are two Child PGs
 * Commit changes
 * Export Parent without services

At this point if you restart 1.18.0 nifi, it comes back up fine showing Parent as up to date.

Now go to 1.19.1 NiFi:
 * Import Parent flow definition
 * Start version control
 * Restart NiFi

At this point, NiFi comes back up and says there are local changes to commit, even though there weren't before restart. See attached screenshot.

On a similar note, if you try to perform the initial steps using latest NiFi, you get an error trying to import the exported Child PG, and the error says one of the components for the connection can't be located. So this seems like a related issue involving something that changed with versioned component ids.
