Since many years, the CPW is for me a treasure of knowledges and I decided to write a script to properly import pages, users, files and history from WikiSpaces to MediaWiki.Gerd Isenberg wrote: Current plans are to convert it to MediaWiki - despite bugs and problems by wikispaces to convert its native wikitext to other formats, we managed to get a ~140 MB MediaWiki.zip, but so far no way to preserve the complete history for CC BY-SA conformance.
The script uses Wikispaces SOAP API to import pages content and history and WebDAV to import files.
The script can be downloaded here :

I hope it will be useful for your migration.
