Migration / import from other systems like phpwcms and PostNuke#

My aim is to collect here links to tips and threads on this forum about migrating from other systems. Many people are importing existing documents, news and users from other CMS systems and thankfully some are sharing their methods.

This is probably not a complete list - please post a reply with any links that are missing. I will then edit them into the top post.

Any system WebusersImport - Manager module allowing you to import webusers from a CSV file.

phpwcms phpwcms to modx migration - a simple sql script to import posts from phpwcms into modx db for given category

PostNuke [Utility] Migrating stories and links from PostNuke - command-line PHP scripts for import

Xoops News Migrate XOOPS News to ModX - PHP script to import from an XOOPS DB

the link to the Xoops import thread is the same as postnuke.

I have a HUGE xoops site I would like to switch over
