Seamless Migration of NordiskRegnskab to a Distributed Cloud Infrastructure
We helped NordiskRegnskab modernize its legacy system by moving from a single-server setup to a distributed cloud — improving scalability, data reliability, and overall performance without disrupting daily operations.
Introduction
As NordiskRegnskab’s client base expanded, its legacy single-server system could no longer keep pace with demand. The accounting firm partnered with Chainweb to migrate to a distributed, cloud-based infrastructure — gaining scalability, reliability, and faster performance across operations. This transformation not only reduced maintenance risks but also positioned NordiskRegnskab for long-term digital growth and improved service delivery.
Project Overview
NordiskRegnskab relied on a single on-premise Windows Server 2016 machine to run all accounting operations and client data — a setup that became a growing risk as the business expanded:• Performance bottlenecks during high-load reporting cycles slowed service delivery.• No redundancy, meaning any hardware issue could bring operations to a halt.• Compliance pressure increased as GDPR data-handling standards evolved.To protect uptime and enable future growth, the company needed a migration plan that would deliver continuous availability, regulatory confidence, and effortless scalability.
The Migration
Target Platform
To ensure scalability, security, and compliance, the team chose Microsoft Azure Distributed Cloud (VM + SQL Database + Blob Storage) as the migration target. Azure’s native GDPR compliance, EU-based data centers, and seamless integration with Microsoft’s ecosystem provided a trusted, future-ready foundation for NordiskRegnskab’s digital infrastructure.
Data Migration Process
Implementation Strategy
The migration followed a phased approach to ensure stability and transparency at every step:

Data Migration Process
- Database (SQL Server → Azure SQL Database): Migrated critical data in controlled batches using Azure Data Migration Service. Automated integrity checks after every import guaranteed data accuracy.
- File Storage (local HDD → Azure Blob Storage): All sensitive client documents and financial reports were securely transferred via encrypted channels (AzCopy), ensuring full compliance.
- User Accounts & Access Control: Azure AD integration streamlined authentication — only verified personnel retained access, enhancing security and audit readiness.
- Testing: A full pre-migration environment simulated live conditions. The final cutover took place outside business hours, limiting downtime to under 2 hours with zero data inconsistencies.
Implementation Strategy
The migration followed a phased approach to ensure stability and transparency at every step:
- Phase 1: Archived and non-critical data transferred to validate performance and connectivity.
- Phase 2: Core database and active records migrated with continuous monitoring.
- Phase 3: Final cutover of live systems, DNS synchronization, and real-time validation to confirm data integrity.

- User Accounts & Access Control: Integration with Azure AD streamlined permissions, ensuring safe access only for verified employees.
- Testing: The entire process was validated in a mirrored environment before launch. The final migration happened outside office hours, resulting in less than 2 hours of downtime and zero operational disruption.
Implementation Strategy
The migration followed a controlled three-phase approach for stability and transparency:
- Phase 1: Transferred archived and non-critical data to test performance and reliability.
- Phase 2: Migrated the active database and current-year data under continuous monitoring.
- Phase 3: Completed final cutover, DNS switch, and live system validation — confirming full data integrity and seamless user access.
Impact
- Business Continuity: Migration completed with zero disruption — accounting operations and client access continued without interruption.
- Scalability: The new distributed setup allows resources to scale instantly during peak seasons, maintaining high performance even under heavy load.
- Security & Compliance: End-to-end encryption and Azure’s GDPR alignment ensure full protection of sensitive financial data and regulatory peace of mind.
- Cost Optimization: The firm replaced expensive on-prem hardware with a flexible, pay-as-you-go cloud model — reducing maintenance costs and improving financial predictability.
