Some preliminary work exists if you're moving a CMS/Wiki to Tiki. These tools are not complete or built with perfection in mind, but can be most useful to someone willing to fix some problems and enhance some aspects.
- Wikini (Wakka based wikis)
- phpBB (a nice forum and groupware)
- TWiki - an Enterprise Collaboration Platform
We are looking for new data conversion scripts from other popular cms, blog, forum applications. Please contribute! You're also encouraged to contribute fixes or documentation on the existing scripts.
