Migrating from PunBB Forums to Drupal
rdilauro - March 5, 2008 - 19:55
Right now I have 4 systems running PunBB as the Forum manager. I also am a moderator for a large medical site that is thinking about migrating from PunBB to Drupal.
I was wondering if anyone out there has done something like this. I saw a few posts about PhPBB, so I am sure it is similar.
In terms of the database. We have over 7000 members with over 11,000 topics. Is there a way
to migrate some of that information from PunBB (MySQL DB) to a Drupal system?

converting...
I did a bit of looking around, and I don't believe there is currently a module for converting information in a PunBB database directly to drupal, so one would have to be written. It is indeed possible, though. Both your topics and your users can be migrated.
First, however, you should configure an existing Drupal site (with forums) to meet your needs).

worked for us (8000+ topics, 2000+ members), the only issue was the "Movepost" plugin which was installed on PunBB messing up some comment id's when migrating to PhpBB. Also, user names might need some reworking, as PunBB accepted non-numeric and non-alphabetic characters in user names...
Good Luck!
