Hello,
i’m trying to import my IPB 3.4 forum (200k users, 1.5M posts) into Discourse using ipboard.rb
Importing users went fine, but i encounter below error when importing topics:
**Traceback** (most recent call last):

**DETAIL: Key (val)=(discussion#50554) already exists.**
The error message is clear, but my question is how can i identify what is the duplicate key ? Where to look ?
At first, i thought it was IPB topic_id = 50554, so I deleted the record and relaunch the import script but I got the same error.
I’m not sure where to look from here…
Thank you
