How big is your outer ring? If it is a 52, you may have to upshift the front derailleur a little more slowly and carefully. Also, in the small-small combinations, your chain will sag a bit if your derailleur cannot take up the additional slack. Neither of these problems requires any derailleur adjustment, other than perhaps tightening the pivot positioning screw, to rotate an older derailleur clockwise (downward and backward, thereby increasing chain tension).
I used to gear my Nishiki 50-47 / 14-16-18-20-23 (half-step), which I changed to 50-42 / 14-23 (Alpine or 1.5-step) on days I planned to ride through the hills of west-central Los Angeles or Malibu/Topanga. The gearing change entailed simply swapping the inner chainring, a 5-minute operation.
