Upgrading Zend Server on DEB

Zend Server does NOT support upgrades from previous major versions to later major versions. For example, upgrading from 8.x to 9.0 is not supported. You will need to uninstall the earlier version before installing the new version. However, upgrading within a major release, for example from x.1 to x.2, is supported.

 

To install Zend Server, see instructions for uninstalling Zend Server on DEB and perform a clean installation.
