Anyway, this one supersedes that one, and if a moderator would like to remove the old one, please do - with apologies for any redundancy on my part.
Basically, the only residual issue is that I don't seem to be able to restore series metadata. I copied the kepub files directly from the local backup I made of the Kobo files (including all the files/file structure from the device). That (to my surprise) seems to have retained/restored collections data, for example, as well as covers and other images - the only thing that seems to be missing is series data.
So, the question now is: Is it possible to retrieve the series data from the "metadata.calibre" file on the device, which is also of course in the local backup? I haven't plugged in my device yet, because I don't want to risk Calibre "syncing" anything on it, with resulting metadata loss. This might be excessive caution on my part, or even superstition. But if anyone can assure me that I can just plug in, with the right options selected in the Calibre settings, I'll give that a go.
