Replacing Interface Modules
You can replace an interface module either with the same type of
module or with a different type of module.
If the number of ports in the old module and the new module are the
same, the mapping between the Interface IDs and the port names does
not change. No further action is needed after you have replaced the
module. However, if the number of ports in the new module is not the
same as in the old module, you may need to modify the interface
definitions. For more information, see the
Interface Module Guide
