Upgrading the Liferay DXP Data

Now you’re ready to upgrade the Liferay DXP data. The upgrade processes update the database schema for the core and your installed modules. Verification processes test the upgrade. Configured verifications for the core and modules run afterwards, but can be run manually too.

Here are the ways to upgrade:

  • Upgrade everything in one shot: Use the upgrade tool to upgrade the core and all the modules.

  • Upgrade the core and the modules separately: Use the upgrade tool (recommended) or Gogo shell to upgrade the core. Then use Gogo shell to upgrade each module.

If you are upgrading from Liferay Portal 6.2 or earlier, use the upgrade tool to upgrade everything. It’s the easiest, most comprehensive way to upgrade from those versions. Since version 7.0, however, Liferay DXP’s modular framework lets you upgrade modules—even the core—individually. A helpful practice for large databases is to focus first on upgrading the core and your most important modules; then back up your database before continuing upgrades. Upgrading is a flexible process that adjusts to your preferences.
