There isn't any way, other than restructuring the RRD.
I've heard there are some tools that will help port data from one RRD
to another with different row setups - but doing so is a fairly
IMO, the value of keeping the old RRD's around is usually not enough
to justify reworking the data. But everyone's needs and wants are
different - so suit yourself.
But you either have to modify the RRD's and port the data, or delete
the old RRD's and let SP create new RRD's with the new row paramaters.
[On a side note - how much data does 20 pings produce, vs 5? IMO, the
additional load is rather small, and might not be worth messing with -
which would solve your historical data problem too.]
