Zend Server for IBM i 6.2 supports both new installations and upgrades from Zend Server for IBM i 6.0.1 and 6.1. Zend Server for IBM i 6.2 can be installed as a new installation on a partition running Zend Server for IBM i 5.x, and both can be run at the same time, allowing for a migration from version 5 to version 6.

Zend Server for IBM i 6.2 installation files can be downloaded here

For new installations, please choose one of the new installation files. For first time installations, the "6.2.0 upgrade from 6.x" installer should not be used (this installer is for upgrades from 6.0.1 or 6.1.0 only).

Choose either PHP 5.3 or PHP 5.4. First time installers should usually choose the latest version of PHP, unless they are planning to use a third party PHP application that is not compatible with that version.

For detailed installation instructions, please refer to the Zend Server for IBM i Installation Guide. For upgrades from Zend Server for IBM i 6.0.1 or 6.1, please choose one of the "6.1.0 upgrade from 6.x" install files. Please choose the upgrade installer that matches the currently installed version of PHP (5.3 or 5.4). Detailed installation instructions are included as a text file in the downloaded folder.

After installing Zend Server for IBM i, please return to the download page to check for any Hotfix or XML Toolkit updates. If any exist, please download and apply them. Each update will include instructions for installation. Please check back periodically for updates. You can also receive notifications of updates by signing up for the "Zend PHP Monthly Updates for IBM i" email newsletter, available at your My Account page.
