you should be able to form the WSFC without uninstalling the existing instance.First things to check are the OS and hardware between the existing server and its intended
failover cluster partners, are they compatible?
Once the cluster has been created enable AlwaysOn for the instance via SQL Server configuration manager
Hi Perry,
Thanks for the reply. From what I've read adding the WSFC components to the server after SQL has already been installed is problematic and one of the ways around it is to uninstall & reinstall SQL.
I neglected to mention in the Original Post that these servers are Hyper-V VM's, so 'hardware' compatibility isn't a problem.
Do you have any experience (good or bad) with installing the WSFC components to an existing SQL Server and setting up a Cluster and AOAG's?
