  • Used Zammad version:
    New Zammad: 6.5.2-1761942778.51909d1d.noble
    Old Zammad: 6.6.0_alpha Release: 1757682252.c2979390.centos9

  • Used Zammad installation type: package

  • Operating system:
    New system: Ubuntu 24.04.3 LTS Noble
    Old system: Rocky Linux 9.6 Blue Onyx

  • Hello,
    I have to migrate the database from old zammad to new zammad.
    The issue is in versions… How can I downgrade from 6.6 to a stable version 6.5 of zammad on old server and migrate the database to a new server.
    I have installed a new enviroment in 3 server architecture App server, Databse server and Elasticsearch server.
    Everything is connected and working just the database is the problem now.
    If you have experiance with this or tips on how to do it, please share.

Old server DB: RHEL Rocky
{adapter: “postgresql”, database: “zammad”, pool: 50, timeout: 5000, encoding: “utf8”,

New server DB: Ubuntu
{:adapter=>“postgresql”, :database=>“zammad”, :pool=>50, :timeout=>5000, :encoding=>“utf8”,

You shoudln‘t downgrade Zammad-Versions. The best moment to do the switch from develop to stable is a release.

Is using develop on the new host no option…?

Apart from that, the migration process is available on docs.zammad.org.

OK, thank you.

I will update both instances to the latest version of develop. And on next relese i will go to stable version.

In documentaion is there any info on how to change from develop to stable version?

No but this will help you, sorry for the quality.

As helpfull this is I can’t risk going test versions… Unsless you can pursuade me that 7.0 is stable enough to handle Customer support and another 15-20 departments :sweat_smile:

Didn‘t you day that your current active instanxe runs on alpa…? :rofl:

Hahahhaa yes 6.6, this was legacy from old administrator who installed it and now I am trying to create a much more stable enivroment for this system.
:sweat_smile:

8

I don‘t see much of a difference to continue that path until Zammad 7.0 comes to be honest.

9

I have to migrate from old server to new, and installing dev on new put’s me on 7.0 and old one then needs an update as well.
Is it possible to install last 6.6 from packeger.io?

7.0-alpha and 6.6-allha inho are the same. 6.6 was last communicated 2 months ago. That means you‘re also missing security updates.
