Overview
Make sure to read general information about upgrading first.
Upgrade procedure
1 Stop Zabbix processes
Stop Zabbix server to make sure that no new data is inserted into database.
# service zabbix-server stop
If upgrading Zabbix proxy, stop proxy too.
# service zabbix-proxy stop
It is known to be possible to upgrade the server only and have older, yet unupgraded proxies report data to a newer server (the proxies can't refresh their configuration though). This approach, however, is not recommended and not supported by Zabbix and choosing it is entirely at your own risk.
2 Back up the existing Zabbix database
This is a very important step. Make sure that you have a backup of your database. It will help if the upgrade procedure fails (lack of disk space, power off, any unexpected problem).
3 Back up configuration files, PHP files and Zabbix binaries
Make a backup copy of Zabbix binaries, configuration files and the PHP file directory.
Configuration files:
# mkdir /opt/zabbix-backup/ # cp /etc/zabbix/zabbix_server.conf /opt/zabbix-backup/ # cp /etc/apache2/conf-enabled/zabbix.conf /opt/zabbix-backup/
PHP files and Zabbix binaries:
# cp -R /usr/share/zabbix/ /opt/zabbix-backup/ # cp -R /usr/share/doc/zabbix-* /opt/zabbix-backup/
4 Update repository configuration package
To proceed with the update your current repository package has to be uninstalled.
# rm -Rf /etc/apt/sources.list.d/zabbix.list
Then install the new repository configuration package.
On Debian 9 run:
# wget https://repo.zabbix.com/zabbix/3.4/debian/pool/main/z/zabbix-release/zabbix-release_3.4-1+stretch_all.deb # dpkg -i zabbix-release_3.4-1+stretch_all.deb

# wget https://repo.zabbix.com/zabbix/3.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.4-1+trusty_all.deb # dpkg -i zabbix-release_3.4-1+trusty_all.deb
Update the repository information.
# apt-get update
5 Upgrade Zabbix components
To upgrade Zabbix components you may run something like:
# apt-get install --only-upgrade zabbix-server-mysql zabbix-frontend-php zabbix-agent
If using PostgreSQL, substitute mysql with pgsql in the command. If upgrading the proxy, substitute server with proxy in the command.
6 Review component configuration parameters
See the upgrade notes for details on mandatory changes.
For new optional parameters, see the What's new section.
7 Start Zabbix processes
Start the updated Zabbix components.
# service zabbix-server start # service zabbix-proxy start # service zabbix-agent start
8 Clear web browser cookies and cache
After the upgrade you may need to clear web browser cookies and web browser cache for the Zabbix web interface to work properly.
Upgrade between minor versions
It is possible to upgrade minor versions of 3.4.x (for example, from 3.4.1 to 3.4.3). It is easy.
To upgrade Zabbix minor version please run:
$ sudo apt install --only-upgrade 'zabbix.*'
To upgrade Zabbix server minor version please run:
$ sudo apt install --only-upgrade 'zabbix-server.*'
To upgrade Zabbix agent minor version please run:
$ sudo apt install --only-upgrade 'zabbix-agent.*'
