ok... so I made this tool to copy content around between wikis... this is a beta release so it hasn't been tested in a ton of ways, but it worked pretty well for me.
You can use this to copy pages from one wiki to another... it may pick up your internet explorer pbwiki login and be able to edit wikis for you automatically, but if it can't then there's the option to login with your email/password...
the link for the tool is here:

Given time, you could use it to copy a wiki...
like this one for instance...
http://tsots.pbwiki.com
to
http://copytest.pbwiki.com or... to be extra fancy, to a 2.0 wiki like
http://copytest2.pbwiki.com
The somewhat manual nature of the copy should make it slow enough that you wouldn't trigger any pbwiki spam filters (a problem with bulk copy scripts that I've created in the past) so it should work well... very curious to hear your thoughts...
