Move Host to different FC switch, does device file change?

I want to verify that Tru64 uses WWID to determine disk device "sameness". I want to know that if I move a host's FC cables from one FC switch to another and I take care of port-zoning changes, that the device files won't change on the host.

That is right. Tru64 uses WWID to determine disk device.
As you said, take care of port-zoning.

Above is correct. WWID is all that Tru64 cares about.
