From on-premises to Azure: successful IT modernisation
Maximum scalability and availability without tying up capital.
As part of a comprehensive IT realignment, RIMERIT replaced the existing on-premises infrastructure with a modern cloud solution, with the goal of optimising processes and sustainably reducing operating costs. The result is a modern, practical IT setup with a clear strategy, automated device provisioning via Windows Autopilot, and central management of more than 250 workstations through Intune.

With Azure Virtual Desktop, the ERP system can be used independent of location. The internal IT team was strengthened, know-how was built up, and specialised software was packaged. A well-designed network and cost concept, as well as the introduction of Kyocera Cloud Print & Scan, round off the solution. RIMERIT acts as the exclusive partner for IT services and procurement—holistic, future-proof, and client-focused.

Tenant-to-tenant migration to ensure compliance with data residency requirements
Even complex migrations can be carried out without interrupting business operations — provided they are planned properly
medisana GmbH, a mid-sized company in the medical and wellness products sector, faced the challenge of modernising its established IT landscape while also meeting regulatory data residency requirements. The existing Microsoft 365 tenant was not hosted in a European region, creating increasing compliance, data protection, and governance risks.

RIMERIT planned and delivered a highly complex migration from a non-European Microsoft 365 tenant to a European Microsoft cloud region in order to meet data protection and data sovereignty requirements. As part of the project:

● More than 8 TB of SharePoint data was structured, validated, and securely migrated
● Around 500 Exchange objects — including mailboxes, distribution lists, resources, and rules — were migrated

Thanks to a carefully planned coexistence phase, detailed migration waves, and transparent communication, business operations continued without any noticeable disruption.

To further strengthen the IT environment, RIMERIT implemented two-factor authentication via RADIUS. This significantly enhanced the security of VPN and infrastructure access while also aligning with modern compliance and security best practices — with high user acceptance.

Precision with secure IT
Precision requires systems that work-reliable IT is essential.
Scalability and high availability - without relying on the cloud.
That is exactly why the Essen-based engineering firm Ripkens Wiesenkämper has relied on RIMERIT for years to continuously develop its digital infrastructure. As the company grew, so did the demands on its IT landscape: secure data storage, flexible working models, and modern communication without downtime in day-to-day operations were essential.

The solution: RIMERIT provided a cloud telephony system, integrated reliable storage and network systems, and ensured scalability with an S2D cluster. Software and licence management further reduced the workload on internal teams.

The result: stable systems and seamless communication. A real game changer is the integration of automated processes to optimise interfaces—eliminating friction and significantly relieving internal teams.

Digital transformation for efficient workflows
Efficiency is the decisive factor in business processes. The foundation is modern, secure IT with flexible systems.
Tailored IT solutions don’t just work -they anticipate what’s next.
Trust in a cooperative partnership for all IT matters—this is what has connected Werner Lüke GmbH with RIMERIT since RIMERIT was founded. With the clear goal of making workflows simpler, more efficient, and more modern, the company was supported step by step in its digital development.

The solution: Using a lift-and-shift approach, Microsoft 365 was implemented as the central platform. Today, Werner Lüke GmbH works on a powerful Azure instance instead of a local server. In addition, the orgaMAX ERP system was integrated, including digital processes, automations, and intelligent dunning. All solutions were implemented consistently in compliance with GDPR and GoB requirements.

The result: Werner Lüke GmbH now benefits from fully digital workflows, stable systems, and a clear efficiency gain in day-to-day operations. Business processes are transparent, the IT environment is future-ready, and the company is comprehensively supported as part of a managed service.
