if you program in Perl, RRD::Tweak module might be helping. I wrote it exactly for that -- to be able to manipulate RRD structuire in a flexible way.

>Unable to find a script to merge my RRD files as I wanted, I’ve taken to writing my own generic one.
>This new script will merge one or more RRD files, which do not need to have the same DS or RRA definitions, to make a single RRD. It can preserve a configurable list of DS over the set, building different RRA from whichever available RRA match the closest, merging RRA where they cover different time windows. You can specify longer or shorter RRA length, and even change the step value as you go (though this is not yet working quite right). It should also be able to use one RRD to fill in the gaps in another, though this is still work in progress.
>It doesn’t seem to work with HW RRAs yet, and I haven’t tested with calculated DSs.
>Is there anyone out there who’d like to have a copy for testing purposes, and feed back patches/requests/bugs?
>The motivation for this script is to migrate our MRTG system (32bit, multiple archived copies of RRDs) to our new system (64bit, single extra-long RRD) but it makes sense to support a more generic set of requirements.
