MAC addresses for SVIs are supplied by the chassis so they change.
L3-interfaces get their MAC address from the module.

Also the STP bridge ID changes, since it's also the "base MAC address".

I think, but am not sure, that the "ifindex persist" in configuration
and the resulting persistent data on flash will survive between
chassis'.

When we have swapped things like this we have always completely
redefined the device, i.e. new name, new entries in
management/measurement tools et cetera. Running SXF means there's a
great deal of service alignment between the two platforms (if not
complete), but I personally wouldn't consider swapping chassis to a
different model a simple "replacement" task.
