Liferay 6.1 EE to 6.2 EE Upgrade for a global Fortune 500 engineering corporation

XTIVIA and the “smart buildings” business unit (multi-billion dollar in annual revenue) of a global Fortune 500 engineering corporation have enjoyed a multi-year, multi-project, end-to-end Liferay implementation relationship. As part of this ongoing relationship, XTIVIA undertook a major upgrade of the client’s AWS based clustered Liferay environment from v6.1 EE to v6.2 EE, and completed the upgrade in a 4 calendar week period. In this upgrade project, XTIVIA had the advantage of knowing the existing environments, code base, deployment automation scripts, and site/content setup. Additionally, XTIVIA had architected the client’s code base to abstract all Liferay API dependencies in a manner that made it very easy for us to identify any changes. So, despite an extensive Liferay implementation, and a content repository running over a 100GB, XTIVIA was able to draw up an upgrade plan, execute needed code updates, perform test Liferay content migrations, create new Liferay v6.2 environments on AWS (to allow for seamless cutover and easy backout if needed), and go live all in a matter of 4 weeks.
