Cloud first for the law firm. Thouvenin modernises in six months.
How the renowned Zurich law firm migrated its outdated IT infrastructure entirely to the Microsoft Azure Cloud in six months and handed operations over to Baggenstos.
Thouvenin Rechtsanwälte, a renowned law firm with a tradition of excellence, decided on a comprehensive IT modernisation and initiated the project. The aim of the project was to create a future-orientated, flexible and agile IT infrastructure based on the cloud-first strategy and seamlessly integrated with the Microsoft Azure Cloud and Microsoft 365.
The transformation, embedded in Baggenstos' 'Modern Work' concept, included the complete migration of the data centre to the Azure Cloud as well as a comprehensive modernisation of the application and device landscape. In addition, Baggenstos' innovative and future-orientated managed service 'Operation Care' was implemented, which includes the out-sourcing of operating services.

Facts & Figures
Initial situation and objective
Thouvenin Rechtsanwälte's IT infrastructure no longer met the requirements and was five years old. It was no longer optimised to support the firm's targeted growth. The aim was to fundamentally modernise and migrate to the cloud to increase the efficiency and flexibility of the IT systems. The focus was on fulfilling the company's requirements. In addition, solutions were to be found that would promote a long-term partnership and have a future-oriented focus.
Key figures
- Users: 40 mobile workstations
- Application server: 13 virtual servers as IaaS
- No local IT infrastructure (only firewall, network and wireless LAN)
- Project duration: 6 months
Solution & Implementation
Baggenstos implemented several sub-projects, including the creation of an Azure Landing Zone for connecting to the cloud, the migration of email and backend systems and the introduction of new Microsoft security and device management solutions. Below you will find an overview of the implementation:
- Integration in Microsoft 365 and Microsoft Azure Cloud: A cloud computing platform for the transformation of applications and the replacement of classic file servers, which facilitates the development, provision and management of cloud services. As part of this integration, the entire infrastructure was successfully connected to Azure and the data migration was carried out smoothly.
- Microsoft Azure Virtual Desktop (AVD): Enabling remote working and efficient implementation of application deployment. AVD also promotes flexible, device-independent working.
- Security: Strengthening identity, cloud and device security to improve the security and compliance of applications and services.
- Modern Work: Focus on improving simplified communication through modern working methods, especially in the area of collaboration, such as sharing and joint editing of documents between employees, but also in collaboration with external clients and partners.
Baggenstos successfully interpreted the requirements of Thouvenin Rechsanwälte and developed a customised service model that relies heavily on Microsoft expertise in key areas.
Challenges
The biggest challenge in the project was to migrate the existing business applications without disrupting day-to-day business, while at the same time operating old and new technologies in parallel. Older industry applications in particular, which were dependent on local file servers, had to be operated locally with a hybrid solution for a transitional period.
Each industry has specific software requirements, and the flexibility to continue supporting legacy systems during the transition phase was critical to a smooth transition. This was mastered through careful planning and implementation. The migration was accompanied by on-site training for employees on 'Modern Work' and the new business applications.
Results
The new IT architecture enables flexible workplace design and faster customisation. The data is secure and easily accessible, which shortens the lead times for further developments.
- Improved flexibility and scalability of the IT infrastructure.
- Increased efficiency.
- Successful introduction of Remote workstations.
- Modern tools for the daily, secure and close co-operation of employees, clients and partners.
- More reliable Support through the comprehensive managed service 'Operation Care' in the outsourcing model. This essentially includes monitoring, maintenance of the IT environment, cloud cost management and the regular exchange of information as well as the service desk supplemented by an on-call service.
With its tried-and-tested technological solutions, Baggenstos has created a uniform, standardised environment for Thouvenin Rechtsanwälte and has made a significant contribution to promoting flexibility, security and efficiency within the company.
Why Baggenstos?
Thouvenin Rechtsanwälte was convinced by Baggenstos' expertise in Microsoft technologies as well as its experience and trustworthiness. The high level of Microsoft expertise promised seamless integration of state-of-the-art solutions, while the transparency and proactivity created trust. Furthermore, Baggenstos' cost-efficient managed services were a key factor.
Another decisive aspect was Baggenstos' cloud-first strategy, which perfectly matched our need for a flexible, scalable and future-proof IT infrastructure. Baggenstos thus offered an ideal combination of technical expertise and strategic orientation.
Many thanks for the good cooperation
We are delighted with the successful completion of the project and would like to thank Thouvenin for the trust they have placed in us. Since completion of the project, Baggenstos has also taken over the ongoing support of the IT services in the future-orientated managed service 'Operation Care', thus ensuring smooth and secure operational processes.

We offer modern services and need a future-oriented IT foundation. Working with Baggenstos was decisive for the success of this project.

About
Industry & size
Thouvenin Rechtsanwälte is a partner-managed law firm in Zurich with decades of experience. The firm is characterised by a lean organisation and flat hierarchies – the partners look after their mandates personally, from acquisition to implementation.
Core business
Comprehensive legal advice for companies and entrepreneurs. The partners see themselves not only as lawyers, but also as entrepreneurs – they know the needs and mindset of their clients. The result is long-term partnerships rather than one-off mandates.
Special feature
For a firm that works with confidential mandate data, security and compliance are non-negotiable. At the same time, day-to-day collaboration with clients and external partners requires a flexible, modern IT – a tension that made the cloud migration particularly demanding.
IT environment
40 mobile workstations and 13 virtual servers. The previous infrastructure was five years old and no longer optimally positioned to support the firm's targeted growth. Only the firewall, network and WLAN remained on site.
