I have to assume the RRD files are setup the same.  If so:

- At the same moment create a dump on both platforms.
- Create a new ascii file, using the recent part of one
  file and the old part of the other file.
- restore the newly created file on the desired platform

This is something you need to do by hand (using tools of course).
Get yourself up to speed on the format of rrdtool dump files,
it isn't that hard.  The date and time per row is specified in
the xml file, the properties of each RRA are specified and so on.

Much of what looks like rudeness in hacker circles is not intended to give
offence. Rather, it's the product of the direct, cut-through-the-bullshit
communications style that is natural to people who are more concerned about
solving problems than making others feel warm and fuzzy.
