How to Upgrade Legacy Systems Like Dynamics SL to Business Central

In today’s fast-evolving digital landscape, legacy systems like Microsoft Dynamics SL can hold businesses back with their limited scalability, outdated architecture, and lack of cloud integration. For companies in Japan and around the globe looking to modernize their ERP infrastructure, upgrading to Microsoft Dynamics 365 Business Central offers a powerful solution that supports flexibility, automation, and future-ready performance. In this blog, we explore how businesses can effectively upgrade from Dynamics SL to Business Central, the benefits of making this shift, and why working with an experienced partner like Sysamic ensures a smooth transition.

Why Move Away from Dynamics SL?

Originally known for its project accounting and financial capabilities, Dynamics SL has served many industries well. However, it comes with inherent limitations:

  1. On-premise only: Lacks native cloud capabilities, increasing maintenance and hardware costs.
  2. Limited integration: Struggles to connect with modern platforms and services.
  3. Manual workflows: Lacks automation, slowing down operations.
  4. Reduced Microsoft support: Ongoing development and enhancements are now focused on Business Central and other cloud-first solutions.

These limitations make it difficult for Japanese and global businesses to remain agile in a digital economy where integration, data visibility, and automation are critical.

Why Business Central Is the Ideal Upgrade

Microsoft Dynamics 365 Business Central is an all-in-one, cloud-based ERP system that offers:
