I have a utility I've written to merge multiple historic RRD files into a 
single RRD with longer RRAs (it was originally written to merge the old-style 
RRD archives from MRTG/RRD/Routers2 into new-style single extended RRD files). 
It can also perform more complex merges from different RRD files with 
non-matching RRAs or DSs.  It pulls older data where possible to make up the 

If you'd like a copy of this, it is included with the latest Routers2 package, 
(2.23beta5) or drop me a line and I can email it to you.  It is written in 
Perl and works by building a new XML for import.
