[wp-hackers] Force a new ABSPATH when moving WordPress?

[onlyunusedname]

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)?
