--------------------------------------------------------------
In case it is helpful, I also have a prototype for a simpler solution, which
avoids adding a separate "live component external CS resolution" step, and
instead takes advantage of the existing resolution code, and is a much smaller
change.

I've verified that this works importing a flow from registry at an older NiFi
version, importing a flow definition with a Process Group creation from file
from the UI, and replacing a PG using the API call noted in this JIRA, whereas
all of these cases fail on the main branch.

> External Controller Service resolution can break with property migration

>
> Key: NIFI-15341
> URL: https://issues.apache.org/jira/browse/NIFI-15341
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 2.7.1
> Reporter: Joe Gresock
> Assignee: Joe Gresock
> Priority: Minor
> Attachments: CS_Resolution.json
>
> Time Spent: 50m
> Remaining Estimate: 0h
>
> When importing or replacing a Process Group, External Controller Services can
> fail to resolve if a component property was renamed between the versioned
> flow and the currently installed bundle using property migration.
> To reproduce in 2.4.0 or later, download attached JSON file representing a
> Process Group Replace request. Then log into NiFi and copy the Bearer token.
> Then create a new blank process group in NiFi and copy its identifier for
> below.
> Next, create a new StandardRestrictedSSLContextService at the root canvas and
> name it "SSL Context Service".
> {code:java}
> BEARER_TOKEN=<paste bearer token>
> PG_ID=<pg id>
> curl -k -vv -X POST
> https://localhost:8443/nifi-api/process-groups/$PG_ID/replace-requests -H
> "Content-Type: application/json" -H "Authorization: Bearer $BEARER_TOKEN" -d
> @CS_Resolution.json
> {code}
> Observe that the SSL Context Service property in the MongoDBControllerService
> now references a UUID instead of the "SSL Context Service" service.
