We have a use case where we need to import content from an EE1 website to an EE2 website (with existing content). I'm guessing it has to be a custom scripting job, but asking here in case someone knows a smart way of doing this.
One idea I guess is to use DataGrab for the import, but we'd still need to do an export from EE1 in XML (or another format which can be read by DataGrab).
