This section provides the steps required for a successful upgrade from Zabbix 6.2.x to Zabbix 6.4.x using official Zabbix packages for Debian/Ubuntu.
Before the upgrade make sure to read the relevant upgrade notes!
You may also want to check the requirements for 6.4.
It may be handy to run two parallel SSH sessions during the upgrade, executing the upgrade steps in one and monitoring the server/proxy logs in another. For example, run
tail -f zabbix_server.log or
tail -f zabbix_proxy.log in the second SSH session showing you the latest log file entries and possible errors in real time. This can be critical for production instances.
Stop Zabbix server to make sure that no new data is inserted into database.
If upgrading Zabbix proxy, stop proxy too.
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).
Make a backup copy of Zabbix binaries, configuration files and the PHP file directory.
# 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:
To proceed with the update your current repository package has to be uninstalled.
Then install the new repository configuration package.

Update the repository information.
To upgrade Zabbix components you may run something like:
If using PostgreSQL, substitute
pgsql in the command. If upgrading the proxy, substitute
proxy in the command. If upgrading the Zabbix agent 2, substitute
zabbix-agent2 in the command.
Then, to upgrade the web frontend with Apache correctly, also run:
Distributions prior to Debian 10 (buster) / Ubuntu 18.04 (bionic) / Raspbian 10 (buster) do not provide PHP 7.2 or newer, which is required for Zabbix frontend 5.0. See information about installing Zabbix frontend on older distributions.
Make sure to review Upgrade notes to check if any changes in the configuration parameters are required.
For new optional parameters, see the What's new page.
Start the updated Zabbix components.
# service zabbix-server start # service zabbix-proxy start # service zabbix-agent start # service zabbix-agent2 start
After the upgrade you may need to clear web browser cookies and web browser cache for the Zabbix web interface to work properly.
It is possible to upgrade minor versions of 6.4.x (for example, from 6.4.1 to 6.4.3). It is easy.
To upgrade Zabbix minor version please run:
