037/2026: Next Generation T7 Web Based GUIs – Reminder Decommissioning of current Java Based GUIs

Deutsche Börse Circular 037/26

1. Introduction 

With T7 Release 14.1 in spring 2026, the T7 Web Admin was introduced as the browser-based replacement for the Java-based T7 Admin GUI. This circular reminds participants of the upcoming scheduled decommissioning of the Java-based T7 Admin GUI with T7 15.0. 

2. Required action 
 

Users of the current Java-based T7 Admin GUI must migrate to T7 Web Admin (available since 23 March 2026 in Simulation and 18 May in Production) before the respective decommissioning dates: 

  • 31 August 2026 for the Simulation environment  

  • 9 November 2026 for the Production environment

3. Details of the initiative 

The introduction of the “T7 Web Clearer” in 2025 marked the first step to the new T7 Web GUI landscape. The replacement of the Java Admin GUI with the “T7 Web Admin” with T7 Release 15.0 represents the next major step in this transformation. 

The transition to a fully browser‑based GUI landscape will be completed with the introduction of T7 Web Trader, which is currently expected for 2027.
