Liferay Experience Cloud (SaaS) is an evolving product with updates and features being released at a steady pace. Amidst that effort, we also want to provide a dependable environment for our customers to be informed and well prepared as they use the platform. This is why Liferay has established a transparent release cadence strategy.
The release strategy consists of three types of release windows, or opportunities, for Liferay to release changes or fixes to the Liferay Experience Cloud. There are three types of maintenance windows:
DXP Maintenance Windows
4 Hours, Regional Time Zone
Weekly DXP maintenance windows are a fixed update window whose time is determined by Liferay, based on the customer-selected deployment region and that region's time zone. During these maintenance windows Liferay will regularly update the running database and the DXP instance.
During this maintenance window, 1-2 short downtimes can be expected almost every week.
Just before the update, Liferay will verify updates install correctly without issues in order to reduce downtime. Liferay will attempt the update on a copy of the production database, checking for data or product issues. Liferay will also execute end-to-end tests to ensure the quality of the update. Liferay and the customer work to establish these predefined test plans ensuring that custom business use-cases are properly covered. If these tasks are successful, then the same process will be completed on the production and the non-production systems together.
If you have any questions, please open a Help Center ticket.
Platform Maintenance Windows
Tuesdays and Thursdays between 8 a.m. and 8 p.m., Pacific Time Zone
Platform maintenance windows are fixed windows used to improve the Liferay Cloud Platform through new releases, configuration changes, or bug fixes. This window is every week on Tuesdays and Thursdays from 8 a.m. to 8 p.m. Pacific Time, or any other time that is communicated at least 14 days in advance. Nearly all releases can be accomplished with zero downtime or outage to the customer's application. As with any system, the larger the change, the higher the risk of unexpected downtime. Liferay will communicate with customers about any known downtime due to maintenance/releases at least 14 days in advance.
Detail and a yearly calendar can be found here.
Emergency Maintenance Windows
If necessary, critical zero-day security or reliability changes can be installed by Liferay at any time without prior notice. Liferay is committed to the uptime of our customer environments and carefully manages uptime when mitigating security and reliability issues.
