Elastic search wont start

Technical assistance

Hi,

I always keep Zammad up to date, but I didn’t realize that elastic search doesn’t also update it self. So now I have Zammad in lates Version 4.0.x but elasticsearch was on 5.6.16. I then updated elastic search to 7.13.2 but elasticsearch wont start. In the log file I can see:

java.lang.IllegalStateException: The index [zammad_zammad_production_ticket/q7t32r3wTC-P5-NJSh0giA] was created with version [5.6.16] but the minimum compatible version is [6.0.0-beta1]. It should be re-indexed in Elasticsearch 6.x before upgrading to 7.13.2.

How can I do that, so that elastic search will start again?

Thanks in advance!

So i restored my VM and did an update to 6.8. Everything seem to work fine after that. so i tried my luck and got to 7.13.2, but elasticsearch wont start with a reason like “something needs to be reindexed, you are on 5.6.16”.
I would like to go to latest Version so i dont have to need to hazzel around with that again in a few months. What do i need to do?

Hey @Dirk23,

you probably need to have a look at the es documentation. They’re pretty straight forward about the recommended upgrade procedure.
