Rerun db:migrate on a CentOS 7 installation


  • Used Zammad version: zammad-5.0.3-1640164755.9ed29355.centos7.x86_64
  • Used Zammad installation type: package
  • Operating system: CentOS 7
  • Browser + version: Firefox

I’ve updated zammad to the latest version and with that updated my postgresql server from CentOS 7 shipped 9.3 to 9.6. It looks like within the installation the rake db:migrate task did not run correctly. I see this error:
E, [2021-12-23T13:34:24.278901 #10093-178540] ERROR – : PG::UndefinedTable: ERROR: relation “core_workflows” does not exist

Is it possible to rerun the rake db:migrate task to get the core_workflows table? How would I do that?

What I’ve already tried:

  • yum reinstall zammad (in the hope that the upgrade scripts will run again)
  • yum remove zammad and yum install zammad did the trick. Now it seems like the missing table was created.


Your only option is to run zammad run rake db:migrate.
That should do the trick - this is also done during an installation or upgrade.

Reinstall thereotically should have triggered that as well.
I know it’s too late in your case, I just wanted to notice it.
