You *could* change the step using dump, edit, restore, but this would not 
give the results you want.  There is no timestamp stored with each data 
point, so changing the step would change the time rrdtool associated with 
each data point.  Double-plus-ungood.  You could get something close by 
dumping the rrd, munging the xml to produce the required update lines, 
creating a new rrd with the new step and updating with the old data. SMOP.
