Updating an Application

Updating an application allows you to upload a new application package for an existing application and base URL. You can also change the values of the application’s parameters during this process. Updating an application is useful, for example, when you have a version update for your application. The flow of the process is as follows:

Updating your application on Zend Server Cluster Manager will update all the nodes in the cluster.  

Important Note:

When updating your application, the server uses the same base URL as previously defined. Changing the base URL  can only be done by deploying it as a new application.

Before updating your application, you must update your application package to reflect the changes.
