> # Replacing a Server with Another Server

> You can use the Replace Server wizard to accomplish the following tasks:

> - Replace a failed server with a new server onto the same port without changing the SAN. The new server gets the same virtual pWWN as the failed server because the virtual pWWN is assigned to the port.
> - Replace a server with a spare server on the same NPV device or a different NPV device, which can be brought online without changes to the SAN. This is achieved by moving the virtual port WWN from the current server port to the spare port.
