In 2025, we laid the foundation for a modern infrastructure through a comprehensive upgrade to TYPO3 13 LTS. The goal was radical simplification: migrating all relevant websites from two fragmented servers to a single, central instance to streamline maintenance and sustainably reduce operating costs. During an intensive project period, our 13-member team successfully executed six Go-Lives:

• lungeninformationsdienst.de
• dzd-ev.de
• helmholtz-munich.de
• allergieinformationsdienst.de
• diabinfo.de
• clever-gesund-info.de

This achievement involved massive development effort: with 3,045 commits, over 88,417 lines of PHP code, and the handling of 1,279 tickets, we established a clean, maintainable code standard directly at the TYPO3 core.

In the second phase of the project, we migrated the platforms to TYPO3 version 13 and created a unified, modern technical foundation. The aim was to significantly simplify maintenance and reduce operating costs—particularly by decommissioning two of the three previous servers. At the same time, the platform was elevated to a new level in terms of performance, accessibility, and SEO.

The technological realignment delivered immediately measurable results. By optimizing the Core Web Vitals and establishing a professional, four-stage CI/CD pipeline (Development, Preview, Release, Production), we were able to reduce average loading times to under 400 ms. In Google PageSpeed tests, the new platform consistently achieves top scores of 100/100 in both SEO and Best Practices. A particular focus was also placed on accessibility: through WCAG compliance (Level AA to AAA) and 100/100 points in high-contrast mode, the sites meet the highest inclusion standards.
