Just change storage.conf so that new articles will be stored in a
different format. The old articles will still be there in the old format,
but new incoming messages will go into the current storage backend per
If you want to actually move articles from one storage format to another,
that's trickier, since that will change the storage API token for the
article and will therefore require changes to the overview and history

I use timehash for this purpose rather than CNFS because timehash still
gives me one message per file, which lets me back up and restore the
messages a lot easier.

No reason other than no one's written it.

No. CNFS buffers are specific to the endianness and alignment of the

I'm not sure these are very good FAQ questions apart from the question
about moving between storage backends (which is on my list of things to
add to the FAQ) and the question about how to filter out particular types
of content in posts; most of them are a bit esoteric.

Please send questions to the list rather than mailing me directly.
