Do a fetch on the RRD you want the info from and update to the new rrd.
I think this would work

@temp=RRD::fetch $Old_RRD AVERAGE
$size_of_temp=@temp
$new_data=$temp[$size_of_temp - 1]
RRD::update($New_RRD:$new_data)

The DS name won't matter in the situation since you are merely updating data with a timestamp and the locations are assumed to be known.

I think that will work.  Syntax needs to be checked.

Hope that helps,
