Dear 3DEXPERIENCE platform users,

We will upgrade the 3DEXPERIENCE platform to R2027x on Saturday, November 21 and Sunday, November 22, 2026. All services will be unavailable during this maintenance.*

Maintenance Overview

*Please note that the completion time may be subject to change. Schedule updates will be reflected in the 3DEXPERIENCE platform SaaS Availability

Before the maintenance

To avoid losing work, please:

• Save all open documents and complete your work before the start time.
• Finish or reschedule long-running operations (for example imports, exports and simulations).
• Pause or reschedule scheduled jobs and integrations that connect to the platform, as they will fail during the downtime.

Action required after the maintenance

Installing the new version is mandatory for all Desktop Apps and Open Apps users (also known as 3DEXPERIENCE Connector apps).** Without it, you will not be able to keep working once the upgrade is complete.

• Review the prerequisites and the upgrade guide before the maintenance.
• Once the 3DEXPERIENCE platform is back online, install the new version from the Compass.
• Connect to the 3DEXPERIENCE platform to access the latest functionalities

Please note that the Java Runtime prerequisite, required by some 3DEXPERIENCE Connector Apps (list available in the Program Directory), will evolve as follows :

• IBM Semeru Runtime Open Edition for Java 25.0.4.0 (JDK) will be a Validated Platform.
• IBM Semeru Runtime Open Edition for Java 25.0.x (JDK) with x >4 will be a Compatible Platform.
• Oracle JDK 25.0.x with x>=4, will be a Compatible Platform. 

What's coming in 3DEXPERIENCE R2027x 

We’re preparing a set of new features and improvements for 3DEXPERIENCE R2027x. The full “What’s New” overview will be published on November 11, 2026 on 3DEXPERIENCE platform user's community  We’ll include it in our reminder email so you can be prepared before the upgrade.

Follow the progress

We will publish live status updates on the 3DEXPERIENCE platform SaaS Availability. If the maintenance runs longer than planned, the expected completion time will be updated there. We will also send a reminder one week before the maintenance.
