Install Zammad 5.3.1 on Debian 12 (Moving Server)

[simoon]

HI,
i have to transfer an Zammad installation from an debian 10 to a new debian 12 server.
so i want to install Zammad 5.3.1 on a Debian 12 but i cannot find valid command.
apt install zammad=5.3 or 5.3.1 is not working with
deb https://dl.packager.io/srv/deb/zammad/zammad/stable/debian 12 main

Is there a way to fix this?

The installation of the latest 6.4.1 works but i need the 5.3.1 to get my old zammad in that version to a new server.

Thanks Alex

You can try to change your source file to the 5.3 stable channel.
deb https://dl.packager.io/srv/deb/zammad/zammad/stable-5.3/debian 12 main
didn’t test it myself but I was updating an old Ubuntu 18.04 server to the latest 4.x package with this way.

Way one: Update your old installation to 6.4.1.
After that you can migrate to a new server.

The other way: migrate the old one with 5.3.1 directly to 6.4.1 on the new Server and start the postinstall script to migrate the database to the latent version.

For your information: the Version 5.3.1 is VERY outdated and has security problems! An update is VERY IMPORTANT!!!

That did not work because of an issue with libssl1.1 the debian 12 has a newer version installed.

That won’t work. Debian 12 support came with Zammad 6.0.

Debian 10 was supported up to Zammad 6.2 btw - so you can upgrade to minimum 6.0, maximum 6.2 and follow the migration documentation from there.

i did the upgrade on the old server, did the backup using the script and imported everything on the new server.

that process is far away from flawless because the zammad 6.4.1. is not running on the debian 12 out of the box because the libssl issue. i installed the lib from the deb 11 repro and now everything is working. thanks for helping.

You’re “updating” it wrong. That’s because of how you do it. You have to hold the Zammad package before.

While we’re throwing with videos around…:
