Concern regarding enbling cluster relocation on an existing Redshift cluster with port 8192

Hi all,

I turned on cluster relocation for one of my redshift cluster which was created in past with accessibility on port 8192. And in doing so I was successful.

The Redshift page on console also shows that the cluster relocation is enabled.

I am going through the Redshift doc - https://docs.aws.amazon.com/redshift/latest/mgmt/managing-cluster-recovery.html and the limitations section says that I can't turn on relocation for a cluster running on port other than 5439. Where as I was able to successfully do so.

Can you please help? Am I missing something here?
