Hello, me and my group of crazy idiots are really close to finally migrate our Vbulletin3 forum into Discourse after having wrote an ad-hoc script that finally manages to migrate all the 21 millions replies from the original database into discourse. Now, we have the problem of links to the topics/r…

This already exists in core, it is called Permalinks, and the existing VB4 importer has code for it script/import_scripts/vbulletin.rb main # Add the following to permalink_normalizations for this to work: # /forum\/.*?\/(\d*)\-.*/thread/\1 …

Did your script create import_ids? If so, even if your didn’t create the permalinks, you can fairly quickly process those to create them.
