Action required! - End of Life Version 2504
Hi Community,
We want to make sure you have enough time to plan ahead: SIMATIC AX Logic Control Engineering version 2504 will reach its End of Life (EoL) on September 30, 2026.
From that date onwards, 2504 will no longer receive any updates, bug fixes, or security patches, and will be out of support.
To keep your environment up to date and benefit from updates, we strongly recommend upgrading to the next Long Term Stable (LTS) release: version 2510.
For more information about the release strategy of SIMATIC AX Logic Control Engineering please take a look at the documentation.
Recommended Next Steps
- Check if you are still using Release Version 2504.
- Plan your upgrade window, including sufficient time for testing and validation.
- Complete your upgrade to version 2510 (LTS) before 30 September 2026.

The migration guide from 2504 to 2510 is available in the documentation.
Remember: only an up-to-date system is a secure system. We encourage you to start planning early to avoid any last-minute disruptions.
Stay AXcited!
