I don't think the DNS Alias will work in this case. I am going from two stand alone SQL servers and two clustered SQL servers, to a new cluster. I can just switch the DNS name, because I have to go from SQLA to SQLCuster\Instance1. Correct me if I am wrong.
Here's the cunning thing. If you get your new SQL instances (in the cluster) to listen on port 1433 you don't have to specify an instance name. You could just connect to SQLCluster without the \Instance1
