NIFI-12330: When synchronizing flow, pause component scheduling until after
property migration has completed (#7994)
> Failure to migrate properties on controller service
> ---------------------------------------------------
>
> Key: NIFI-12330
> URL: https://issues.apache.org/jira/browse/NIFI-12330
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: Bryan Bende
> Assignee: Mark Payne
> Priority: Critical
> Fix For: 2.0.0
>
> Time Spent: 20m
> Remaining Estimate: 0h

> While testing the PR for
> [NIFI-12261|https://github.com/apache/nifi/pull/7991/files#top], I made a
> flow on 1.24.0-SNAPSHOT with GenerateFlowFile -> ConvertRecord ->
> LogAttribute, with all processors stopped. The ConvertRecord processors used
> an AvroReader and AvroWriter, which each in turn used a
> ConfluentSchemaRegistry service. All three services were enabled.
> I then copied the flow.json over to a build of the PR for NIFI-12261 which is
> based on 2.0.0-SNAPSHOT and during start up produced this error:
> {code:java}
> Caused by: java.lang.IllegalStateException: Cannot modify configuration of
> StandardControllerServiceNode[service=AvroReader[id=aac065cf-018b-1000-8c3a-6f1b13f96c34],
> name=AvroReader, active=true] because it is currently not disabled - it has
> a state of ENABLING. Please disable the Controller Service first.

> This was attempting to migrate the properties of the reader/writer which used
> schema access/write strategies that were being removed and replaced with new
> controller services.
