Do you mean you want it to log to the old file, and the new rrd file at 
the same time? I don't believe this is possible without modifying the 
MRTG source code, or simply graphing each source twice (once with 
standard MRTG and once with RRD).

Or do you mean that you want to copy the information from the old MRTG 
files (.log) to the RRD format (.rrd)? MRTG should do this for you 
automatically when you move to rrd.

I don't know of opensource exporters, but RRDEditor at 
www.thetoolsmith.com can suposedly export RRD files into a format Excel 
can understand, I've not tried it though. Their website has changed 
recently, and there doesn't appear to be a link to RRDEditor from their 
home page, but the product forum is still running: 

Or you could look at processing the XML output from "rrdtool dump

I don't understand the question. Didn't you just say you couldn't export 
to excel?
