The Lounge What is on Your Mind? VBulletin 3.8 to Discourse on Docker Migration Test Take Two

  • Step 1: Dump vb database again and all attachments.
  • Step 2: Transfer to discourse host.
  • Step 3:
    discourse=# alter table posts add column vbpostid integer;

  • Step 4: Moved transferred files to shared directory in docker (shared between docker and host)
  • Step 5: Rebuild staging mysql DB in docker / discourse.
  • Step 5: Run modified vbulletin_neo3.rb migration script.
    export IMPORT=1
    su discourse -c 'bundle exec ruby script/import_scripts/vbulletin_neo3.rb'


I think there are some unknown (to me) status counters for topics and posts, because I did not seem to reimport anything but the news topics / threads since the last import.

So, seems I have little choice if I want to refine (transfer likes, fix ICODE tags) is to start migration from scratch.

Let's see after this "does not seem to be working attempt" completes.

The problem seemed to be with postgres and the fact it is running outside the docker discourse app. But frankly, I don't have time or interest to analyze why this "brute force method" failed.

It's easy enough to start over with all lessons learned from the test migrations.

This is the end of test build 2 (and 3).

Now that I have most of the general bugs worked out; and I'm convinced this migration will work, I will setup another server and start new test build 4 from scratch.

Now waiting for DNS to sync / propagate to new server IP address.

Will start new thread for test build 4 soon.

Continue here, test build 4 on a new VPS:
