Search Index Rebuild Fails

  • Zammad version: 5.0.x
  • Zammad installation type: package
  • Operating system: Ubuntu 18.04.6 LTS
  • Browser + version: Edge (Chromium version)

Expected behavior:

Running zammad run rake searchindex:rebuild should rebuild the search index, this is after upgrade Elasticsearch from 5.x to 6.x as I was a bit behind and Elasticsearch in Zammad had stopped running as 5.x was unsupported.

Actual behavior:

rake aborted!
Version 6.8.19 of configured elasticsearch is not supported.

Does anyone have thoughts on what I could/should be looking at to resolve this?

Hey @pntaylor ,

uhm, well. The second line of your output pretty much tells you what’s the problem:

How about upgrading to a supported version?


Hi, appreciate the reply, I perhaps missed something pertinent from my original post. My original version of Elastisearch was 5.x and when I tried to go to 7.x I got the same error so downgraded to 6.x to see whether I needed to go from 5 to 6 to 7 so I’m on a current version.

elastic 7.8+ is officially supported since zammad 5.0+ - hence getting the same error is highly unlikely.

Yeah you can’t do that. That’s why i linked the elastic upgrade guide for you.
You need to follow a certain path when going from 5.x to 7.x.

Please make sure to carefully read that guide and follow it.

If you don’t mind zammad having some limited functionality (considering search/reporting) during the upgrade process you could also drop your zammad indices in es, do the upgrade (step by step) and re-create the indices when you’re done upgrading to the newest version.


Okay I’ll take a closer look and give things a whirl. Appreciate the response

Just wanted to say I’ve got this up and running, appreciate the assistance.
