I am going to migrate one ficon director from DCX to 8510B.   To avoid any mainframe iocds change, I was thought to use the portaddress --bind command to change the fcid of the ports used by storage to be exactly the same as the old DCX.

I was wondering when I perform the portaddress --bind command to change the fcid will it update the port index as well.   My understanding is that the fcid is derived from the port index in hex.
