> In AWS processors the processor level credential properties were removed in 2.0 in favour of AWS Credentials Provider Service. Migration code was added in NIFI-12220.
> The 1.x processors allowed to configure both the processor level Access Key ID + Secret Access Key and AWS Credentials Provider Service properties ({{{}customValidate(){}}} did not check it for some reason). In this case the controller service took precedence.
> The migration process first checks if Access Key ID + Secret Access Key are configured and if they are, it creates a new controller service even if there was another one already in use (and the new may have outdated migrated credential values as the pre-existing service was used effectively in the flow).
> Modify the migration logic to avoid controller service duplication and to use the existing service.
> Also modify the default credential to [anonymous|https://github.com/apache/nifi/blob/ce56117e43c7cdce37ca76d54550a2b45acb508a/nifi-nar-bundles/nifi-aws-bundle/nifi-aws-abstract-processors/src/main/java/org/apache/nifi/processors/aws/AbstractAWSProcessor.java#L415] as it was used if no properties were configured at all.
