Upgrading to Liferay DXP 7.4: Migration Blueprint
Upgrade legacy Liferay instances by auditing custom OSGi modules, running database schema upgrades in isolated staging containers, refactoring legacy hooks to Client Extensions, and verifying templates against Lexicon styling guidelines.
How Do You Perform a Liferay Codebase Security Audit before upgrading?
Direct Answer: Audit custom Java modules for deprecated APIs, servlet mappings, and third-party dependencies, refactoring code to align with DXP 7.4 API classes.
Identify custom modules and hooks before upgrading. Legacy JSP overrides and database integrations will break under 7.4. Re-engineer custom logic to utilize low-code Objects and client extensions.

How Do You Run the Liferay Database Upgrade Tool?
Direct Answer: Configure the database upgrade tool properties. Point it to your database replica, run database checks, and monitor log files for structural errors.
Configure Liferay's upgrade tool in mock docker containers. Execute database upgrades locally, resolving database constraint issues and indexing bottlenecks before touching staging files.

Check status tables after completion to verify all core modules migrated successfully.
What Staging and Cutover Rules Are Best for Production Upgrades?
Direct Answer: Set up staging mirror environments, perform full testing runs, and follow step-by-step rollbacks during final production cutovers.
Test the upgraded database in a sandbox. Verify WCAG accessibility, single sign-on parameters, and integrations before initiating final dns cutover, eliminating portal downtime.

Frequently asked questions
Can we upgrade directly from Liferay 6.2 to DXP 7.4?
No. You must upgrade database tables to Liferay DXP 7.0/7.2 first, then run the final DXP 7.4 upgrade tool.
How long does database upgrade execution take?
Depending on database records and indices optimization, schema migration takes between 2 and 12 hours.
