new FEFs and calcrmf

I am trying to determine whether or not it makes sense to reprocess some
data in the immediate future (as in before the symposium next week).
These results depend strongly on the quality of the ACIS-S response below
0.8 keV or so. First of all, I am using the current ciao so if I use
calcrmf, will the resultant rmf be incorrect? In general, when creating
rmfs with newer FEFs than what was (probably) used in processing the
events in the first, then it is necessary to run acis_process_events also,
right? From the tone of the thread, this not only updates the pi column
but also tips off ciao to use the newer FEFs.

Cheers,
Andy Ptak
