10 Upgrade notes for 6.0.0

Zabbix 6.0.0 is not released yet.

These notes are for upgrading from Zabbix 5.4.x to Zabbix 6.0.0. All notes are grouped into:

  • Critical - the most critical information related to the upgrade process and the changes in Zabbix functionality
  • Informational - all remaining information describing the changes in Zabbix functionality

It is possible to upgrade to Zabbix 6.0.0 from versions before Zabbix 5.4.0. See the upgrade procedure section for all relevant information about upgrading from previous Zabbix versions.

Critical

Audit log

In order to improve audit logging in Zabbix and make the Audit log complete and reliable, the previously existing database structure had to be reworked. During an upgrade DB tables auditlog and auditlog_details will be replaced by the new table auditlog with a different format. Old audit records will not be preserved.

New section Audit log has been added to the Administration→General menu allowing to enable (default) or disable audit logging. Housekeeping settings for audit, previously located under the Housekeeper menu section, have also been moved to the new Audit log section. Existing housekeeping settings will be saved.

API changes

See the list of API changes in Zabbix 6.0.0.

Simple macros replaced by expression macros

The functionality of simple macros has been transferred to expression macros. The existing simple macros will be converted to expression macros during the upgrade. Macros that can not be converted without exceeding the length limit will not be converted with a warning printed in the log file.

Informational

User passwords

Previously, spaces in user passwords have been automatically trimmed in both the User configuration form and the Login form. After the introduction of configurable password complexity requirements, spaces in passwords are no longer trimmed. So users, who thought that they had spaces in their passwords, will not be able to log in as usual and will have to enter their 'old' password without spaces. To continue using passwords with spaces, they will need to recreate their passwords.
