You should be able to just dump the contents of both of you rrd files
and then restore them to the new rrd file. Provided that the two files
hold the same type of date at the same intervals and all that stuff...
rrdtool dump filename.rrd >filename.xml
rrdtool restore [--range-check|-r] filename.xml filename.rrd
