Upgrading Zend Server on Mac OS X

The procedures on this page describe the upgrade procedures for a single Zend Server and a Zend Server cluster on a Mac OS X operating system.
Please read the following restrictions carefully before proceeding.

Upgrade Restrictions

Upgrading Zend Server can only be performed when upgrading from Zend Server 6.x and older to Zend Server 8.x, or when upgrading between Zend Server 8.x versions.

Direct upgrades from Zend Server 5.6 or older can only be performed using a clean installation of Zend Server 8.x. If a clean installation is not possible, you will need to complete a two-step upgrade procedure. For more information, please contact the Zend Support Center.

For a list of limitations and known upgrade issues, see the Zend Server Release Notes.

Note:

When upgrading from a PHP version lower than PHP 5.5, the Optimizer component will be replaced by the OPcache (Optimizer Plus Cache) component.

Using the Zend Repository Installer

The upgrade procedures use the Linux Zend Repository Installer program which includes a simple shell script that automates the process of upgrading Zend Server through Zend's DEB repository.

The script upgrades your Zend Server and PHP versions, according to your current configurations and target version passed. The script will notify you when an upgrade cannot be performed. This occurs in the following scenarios:
