[VMC on AWS] Unable to change PSC registration on vCGW when upgrading PSC from external to embedded.

Products

• VMware Cloud on AWS

Issue/Introduction

Upgrade of vCenter 6.x to a 7.x or later will converge the PSC to embedded as External PSC is no more supported, If the VMware Cloud Gateway is used along with the vCenter, you will need to change the existing PSC registration[external] to the new embedded PSC on the vCGW. 

Resolution

As of now the only option to change the PSC registration in Cloud Gateway is to re-deploy from scratch and join the new PSC SSO domain.
