Thanks for the kind warning.
I've actually already googled my way through the unserialize/serialze
morass. I think I have a solution that is working for this particular set
of minimalist sites. I would never put it forward as a universal solution.
Is there any sort of community-recognized best solution (commercial or non)
for moving a WordPress database in this fashion? Or is it simply never to
be done (and/or case-by-case when it is absolutely unavoidable)?
