From On-Premise to Azure: Successful IT Modernization

Maximum scalability and availability without capital commitment.

As part of a fundamental IT realignment, RIMERIT has replaced its existing on-premise infrastructure with a modern cloud solution, with the goal of optimizing processes and sustainably reducing operating costs. The result is a modern „craftsman IT“ with a clear strategy, automated device installation via Windows Autopilot, and central management of over 250 workstations through Intune.

Thanks to Azure Virtual Desktop, the ERP software can be used location-independently. In-house IT has been strengthened, expertise has been built up, and specialized software has been packaged. A well-thought-out network and cost concept, along with the introduction of Kyocera Cloud Print & Scan, complete the solution. RIMERIT acts as an exclusive partner for services and trade in the IT sector – holistic, future-proof, and customer-oriented.

Tenant-to-Tenant Migration for Data Residency Compliance

Even complex migrations can be carried out without interrupting business operations, provided there is good planning.

Medisana GmbH, a medium-sized company in the medical and wellness products sector, faced the challenge of modernizing its evolved IT landscape while simultaneously meeting regulatory requirements for data residency. The existing Microsoft 365 tenant was not hosted in a European region, which posed increasing compliance, data protection, and governance risks.

The RIMERIT team planned and executed a highly complex migration from a non-European Microsoft 365 tenant to a European Microsoft Cloud region to meet data privacy and data sovereignty requirements. Within the scope of the project, the following was performed:
‍
● Over 8 TB of SharePoint data structured, validated, and securely transferred
● Migrated approx. 500 Exchange objects (mailboxes, distribution lists, resources, rules, etc.)
‍
Through a carefully planned coexistence phase, detailed migration waves, and transparent communication, business operations could continue without noticeable interruptions.
‍
To further secure its IT environment, RIMERIT implemented two-factor authentication via RADIUS. This measure particularly enhanced the security of VPN and infrastructure access while complying with modern compliance and security best practices – with high user acceptance.

Precision with Secure IT

Precision requires functioning systems. Reliable IT is therefore essential.

Scalable and Available – Even Without the Cloud.

For precisely this reason, the Essen-based engineering firm Ripkens Wiesenkämper has relied on RIMERIT for years to continuously develop its digital infrastructure. With the company's continuous growth, the requirements for the IT landscape also increased: Secure data storage, flexible working models, and modern communication without disruptions to daily business were essential.

The solution: RIMERIT deployed a cloud-based phone system, integrated reliable storage and network systems, and ensured scalability with an S2D cluster. RIMERIT also relieved staff burden through software and license management.

The result: Stable, well-functioning systems and smooth communication. The integration of automated processes to optimize interfaces is a true game-changer. This way, friction is prevented and internal teams are significantly relieved.

Digitalization for efficient processes

Efficiency is the decisive criterion for business processes. The foundation for this is a modern and secure IT infrastructure with flexible systems.

Individual IT solutions don't just work, they think along.

Trust in a partnership-based collaboration on all IT matters – that's what has connected Werner Lüke GmbH since RIMERIT was founded. With the clear goal of making processes simpler, more efficient, and more modern, the company has been gradually supported in its digital development.

The solution: As part of a „lift and shift“ approach, Microsoft 365 was implemented as the central solution. Today, Werner Lüke GmbH operates on a high-performance Azure instance instead of a local server. Additionally, the ERP system orgaMAX was integrated, which includes digital processes, automation, and an intelligent dunning system. All solutions were consistently implemented in compliance with GDPR and GoB.

The result: Werner Lüke GmbH now benefits from seamlessly digitized processes, stable systems, and a significant increase in efficiency in daily operations. Business processes are transparent, IT is future-proofed, and the company is comprehensively supported as part of a managed service.
