 I would be very surprised if there was anything else to
do but to toggle
the power supply to 220 volt.  The switch will also change for your 50hz
cycle. 
There isn't anything to change inside the power supply for 50Hz vs 60Hz.

All your software should be built or set to expect a 50 Hz line clock, too,
of course... (unless you like having your clock run at 5/6ths run
at actual speed!)
