[rrd-users] Re: merging old and new data from two rrds

[The infosphere]

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

good luck,

matt
