Rather than have the SCAN configured with new/different IPs, wouldn't it work just as well if it was configured with the VIPs or pubic IPs of the nodes in the cluster?Is it mandatory to use SCAN?

What is the BARE MINIMUM that needs to be configured in regard to SCAN to keep the cluster up and working as it is now? We don't need scalability as we won't be adding more nodes to this cluster.
All the client accessing the cluster right now are working fine connecting through a service we created in the cluster. Will that continue to work as it has been?Yes...You can keep using VIP or Public (not recommended) or use SCAN with one SCANIP. The three options are valid, just make sure that depending on the method chosen will impact in their business.
