rename an Instance in a SQL Server 2008 R2 Active Passive Cluster

  • We have a SQL Server 2008 R2 Active Passive Cluster.   We have one Instance that was setup but never used.

    We would like to change the name from MYSQLINSTANCE\MYINSTANCE to MYSQLINSTANCE

    I have found a few articles that say you can rename the instance in the Cluster.   Has anyone ever done this and\or can you point me to a good step by step article for performing this?

    You currently have a named instance installed. You would need to deploy a new clustered default instance to replace the one you have running.

    IS there a way to rename like this:   MYSQLINSTANCE\MYINSTANCE to MYSQLINSTANCE\MYNEWINSTANCE  without actually uninstalling and reinstalling?
