Q: If you have an old DB from Discourse install, v2.0 > export - import > 2.9 - will it fail or is there a conversion process built into import to allow a successful importation?

Thank you for your replay but simply removing polls is not a solution to duplicate records. I assume somewhere early on the import from phpbb3 was incorrect and created those records. They are valid they just have duplicate UUID’s since original imported did not check for that. Anyway, the solution…
