Importing from drupal
-
I am working on getting a drupal forum migrated to bbpress. I am using the bbpress importer tool. The forum I am migrating has about 4000 topics and 40000 replies. The migration works fine for a few topics, but seems to get stuck at random places after about a 1000 records are migrated. This makes me think that it is not a data problem. More likely some sort of timeout.
Have any of you experienced something similar? I am running things locally with the most recent stable versions of WP and bbpress.
Here is my script. It is not well-tested. Any suggestions for improvements are welcome and feel free to use it as part of bbpress in whatever way you feel like.
