Upgrading Custom Development

Upgrading on 7.4

After upgrading your installation, you must also upgrade your customizations. This includes apps, services, configurations, and more. The steps to upgrade vary for each customization. Generally, the upgrade process follows these steps:

Upgrade the Liferay workspace.
Fix your project’s dependencies and deal with breaking changes.
Upgrade Service Builder services.
Upgrade customization plugins.
In Liferay DXP/Portal 7.4, Liferay module language keys were moved to the Liferay Portal Language module. Many keys were renamed. Check if any of the language keys you’ve overridden have been renamed. For each renamed language key, use the new key name in your language.properties files. See Renamed Language Keys.
Upgrade themes.
Upgrade frameworks and features.
Upgrade portlets.

Upgrading on 7.3 or Lower

The Liferay Upgrade Planner is the recommended way to upgrade custom development to Liferay versions 7.2 and 7.3. It identifies your code that’s affected by breaking changes and offers to adapt your code automatically to many of the changes. See Upgrading Code to Liferay 7.2 for more information.
