    I need to replace 16GB FC 4 port module on FS5200

    Is the WWPN of the 4 ports will change  after the I replace it ?

    It shouldn't. The WWPN is based on the WWNN combined with the PCI slot and port ID of the adapter. In fact, if you replace the node canister the WWPN doesn't change, either.

    It will not.

    WWPNs for Ports in Storage Virtualize products are generated from the WWNN of the Node Canister (which is programmed vpd in MFG and then stored in multiple places) and based on the slot location and adapter port numbering.

    For your reference the replacement procedure is documented here:
