Note for Version 5
Upgrading from Zend Server version 5 requires a migration. Some notes that can help you with the migration process can be found in the online manual:
Migrating from Zend Server for IBM i 5.x
You can find the Zend Server for IBM i updates available here:
Select IBM i in the "Please select your platform" drop down box, scroll down to the "Additional Downloads" section, and choose one of the 'upgrade from' install files. You should choose an Update Installer that matches, or is higher than, the existing version of PHP. For example, if you have 7.0.0 with PHP 5.5, and want to update to 8.0.2 with PHP 5.6, you would select 'Zend Server with Z-Ray for PHP 5.6 (8.0.2 upgrade from 7.x and 6.x)', to download. If you want to stay at PHP 5.5, you would select 'Zend Server with Z-Ray for PHP 5.6 (8.0.1 upgrade from version 6 or higher)', to download. If you currently have PHP 5.4 or earlier, you will need to upgrade to PHP 5.5 or PHP 5.6. The name of the downloaded installer file will indicate both the Zend Server version you will update to and the PHP version. For example:
Once you download and unzip the installation file, you will find a text document in the installation folder that explains how to apply the update as a PTF.
You should also download and install any Hotfixes or Updates that are available for the version of Zend Server and PHP you are upgrading to. These are also found in the "Additional Downloads" section, if there are any. Installation instructions are included in each download package.
During the installation, you will shut down Zend Server. At that time, it is also good to verify that there are no additional locks on PHP from additional Apache instances or from php-cli:
