If you mean that you want to user data from the old.rrd up to a certain time and from new.rrd from that time on, then you could
1. Export both files to XML using rrdexport,
2. write a script (perl?) to create a new XML file from the two exported ones,
3. Import the new rrd file to make a new combined rrd file.
Of course, this assumes you have scripting skill necessary to perform the XML merge. The RRD export XML is a firly simple format, though, so it shouldnt be too hard.
