Discussing ways to upgrade existing hardware in a 2 node Windows 2008 2/SQL Server 2008 R2 (Enterprise) cluster. One idea is to add two nodes to the existing cluster and move the current instances over to them, removing the old nodes when done. The intention is to avoid migrating to a new cluster , needing to repoint apps etc.
The new hardware would have more cores memory etc. Does this present potential problems since the hardware is disimiliar?
thanks
