Keeping your business systems current is critical for performance, security, and functionality. At Z9Works, we’ve successfully delivered numerous migrations and upgrades—from legacy Dynamics NAV environments to the latest versions of Business Central.
Whether it’s a straightforward technical upgrade or a complex migration involving customizations, third-party integrations, and large datasets, we bring both experience and precision to the process. Our team knows how to minimize downtime, protect your data, and ensure a smooth transition so your business can continue to run without disruption.

We handle upgrades from NAV 2009, NAV 2013, NAV 2018, and early versions of Business Central to the latest release. Our approach includes a detailed upgrade assessment, test migrations, and a phased rollout to minimize disruption.
We don’t just move your data — we make sure it’s reliable and usable. From master data (customers, vendors, items) to transactional history, we ensure accuracy and consistency. When needed, we also perform data cleanup, archiving, and re-structuring to reduce clutter and improve reporting.
Older NAV systems often relied on C/AL modifications. During the upgrade, we identify which changes can be replaced with standard functionality, and which should be rebuilt as AL extensions. This future-proofs your system and makes it easier to stay current with future updates.
We make sure your connections to other systems continue to run smoothly after the upgrade. Whether you rely on integrations with e-commerce platforms, logistics systems, payment providers, or reporting tools, we adapt interfaces (APIs, flat files, XML, or custom connectors) to the new version.
Migrating isn’t just about staying compliant — it’s an opportunity to run better. We optimize infrastructure (cloud or on-premises), configure SQL performance tuning, and leverage new Business Central features that improve usability, reporting, and automation.
Every migration includes comprehensive testing — both technical and user acceptance — to validate functionality before go-live. We also provide training and documentation so your team is confident in using the upgraded system from day one.
Our job doesn’t end at the upgrade. We stay with you through stabilization, monitoring issues, and fine-tuning performance. Our support ensures a smooth adoption of the new system.
