Patching Liferay DXP

While we strive for perfection with every Liferay DXP release, the reality of the human condition dictates that releases may not be as perfect as originally intended. But we’ve planned for that. Included with every Liferay DXP bundle is a Patching Tool that handles installing two types of patches: fix packs and hotfixes.

Important: Make sure to back up your Liferay DXP installation and database regularly, especially before patching. The patching tool installs code changes and some of these make data changes (if necessary) automatically on startup.

Certain fix packs (service packs) can include data/schema micro changes—they’re optional and revertible. Module upgrades are applied at server startup by default, or can be applied manually by disabling the autoUpgrade property. You can apply any upgrades using the upgrade tool before server startup.

Note: Patching a cluster requires additional considerations.
