We are already having an SQL Server Enterprise Edition instance running on an Physical Server. Now to configure AlwaysOn Availability Groups
- Can we configure WSFC (Windows Server Failover Cluster) Services on existing SQL server instance?
- Or uninstall SQL Server, install WSFC and then install SQL again? (this may not be a best thing, as they are holding huge DB's.)
As we are planning a 3-node (all are physical machines and currently running SQL instances) cluster, how to move ahead? What options to select from the installation media to proceed with AlwaysOn Availability Groups configuration. Thanks
