A New Website, Part Thirteen - The Conversion

Dec 08, 2006
By Stephen Downes

I've completed the script transferring the data from my old site to the new one. Once I get the mailing lists set up I will be technically ready to switch over (haven't heard any updates from CSoft yet).

The contents mostly copy over OK - all of the data ends up in the database in the right place, which is good. No additional discoveries about the database to report; I just needed to get the conversion script to work.

So, without further ado, here's the script. My data converts to Drupal. Now I need to figure out how to view it (there being utterly no instruction on how to actually view the newly created content types). The dearth of discoverable Drupal documentation continues to amaze me.
