“We went from Teams to GoFAST in just one month!”
Nanterre, the second most inhabited commune in the Hauts-de-Seine department with over 97,000 residents, made a strategic decision in January 2024 at its municipal office: to abandon Microsoft services (Teams, Exchange and the office suite) to strengthen its digital independence.

Faced with the end of its contract with Microsoft and the City Council's decision not to renew it, the city of Nanterre had to quickly adopt an alternative solution capable of replacing Microsoft Teams, then other Microsoft technologies such as MS Office, the file server, and finally MS Exchange. These migrations, particularly that of the 260 collaborative teams in Teams and reorganized in GoFAST, required advanced technical and organizational expertise.
Discover in this article why the city of Nanterre chose GoFAST to replace Microsoft.
As early as June 2022, the city of Nanterre began exploring the possibilities offered by GoFAST by installing the Community version on its own infrastructures. Convinced by GoFAST's ease of use and ability to meet its needs, the city launched a Proof of Concept (PoC) in July 2023 to assess its viability as a replacement for its current tools. The PoC quickly demonstrated GoFAST's ability to replace Teams and offer a robust solution for document management and collaboration, while guaranteeing the city's sovereignty thanks to OnPremise hosting.

After a successful test phase, the city of Nanterre began deploying GoFAST to some of its employees, i.e. 1,000 in phase 1 from January 2024. The replacement of Microsoft solutions, including Teams and SharePoint, was carried out without any service interruption, and the transition was completed in less than a month. Technical scope: The solution is deployed on the city's dedicated infrastructure, with remote maintenance provided by CEO-Vision SAS, guaranteeing continuous platform updates.
Discover in our article the main reasons why organisations are reducing their dependence on Microsoft.
Since adopting GoFAST, Nanterre's agents have fully integrated the solution into their workflows, reducing their dependence on proprietary tools and strengthening internal collaboration. The absence of support requests after migration confirms the smoothness of the transition.
- No longer dependent on proprietary Microsoft solutions
- Security and sovereignty: OnPremise hosting for total data control
- Optimized collaboration, highperformance web conferencing, chat and integrated document management
- Financial benefits: Reduced costs for software licenses and subscriptions to Microsoft solutions
