The FAA is in the process of overlaying existing instrument approach procedures (ILS, VOR, NDB) with RNAV/GPS procedures. The RNAV/GPS procedures have set minima for descent rates (about 317 feet per mile.) The angle of the old approach may need to change and there are certain parameters for the placement of the final approach fix on RNAV/GPS approaches. The folks in Oklahoma City who design the instrument approach procedures sometimes have to move the final approach fix to coincide with the new descent rates which did not previously exist for ILS approaches. You need to bend your brain around this concept a bit, but the OKC designers have been doing it for the past few years.
So now when they move the fix, no matter how slightly they move it, the name must now change. If the BUF controllers have a strong attachment to the old name, like for example the PIT controllers did for WIILE and STARG for Willie Stargell on ILS 10R http://22.214.171.124/d-tpp/0604/00570I10RC3.PDF
when these changes occurred at PIT, then the old name can be held in reserve and used again after the 56 day charting cycle. All charts and aircraft databases are updated at least every 56 days.
