Upgrading Liberty on distributed operating systems

You can use Installation Manager to upgrade your Liberty edition to an offering with more functionality.

Before you begin

  • Make sure that your Installation Manager preferences are pointing to web-based or local repositories that contain the appropriate upgrades for the offering. For example, if you are upgrading from the online product repositories, use the repository for the edition that you are upgrading to.
  • If an interim fix is already installed on the offering that you are trying to upgrade but that specific interim fix is not applicable to the offering to which you want to upgrade, the upgrade will be blocked by Installation Manager. An error message will be generated that indicates that the interim fix is not applicable to the offering. Remove the interim fix before upgrading.

About this task

You can use Installation Manager to upgrade WebSphere® Application Server Liberty offerings in the following paths:
  • WebSphere Application Server Liberty Core to WebSphere Application Server Liberty
  • WebSphere Application Server Liberty Core to WebSphere Application Server Liberty Network Deployment
  • WebSphere Application Server Liberty to WebSphere Application Server Liberty Network Deployment

All Liberty features in your existing installation are compatible with the upgraded installation. Any individual features remain installed when you upgrade.

Important: Some edition-specific addons, such as the feature bundle addons that are included in fix pack 16.0.0.2 and later, might not be compatible with the upgraded edition and are therefore removed. For example, by default the Liberty Core edition is installed with the libertyCoreBundle addon, which contains all features that apply to the Liberty Core edition. If you upgrade to a different Liberty edition, this addon is removed. During the upgrade process, you can install the edition-specific bundle that applies to your upgraded installation.

Procedure

Choose one of the following options to upgrade your installation.
