Dynamics AX is an older ERP product, while Dynamics 365 is a family of business applications. Dynamics 365 covers both ERP and CRM needs, spread across different apps. For most AX customers, Dynamics 365 Finance and Supply Chain Management matter most, since they align with existing finance, manufacturing, and distribution processes. Depending on what your business needs, other apps might come into the picture too.<\/p>\n\n\n\n

Moving over isn’t just a matter of a new product name. You’ll need to think through the right applications, hosting model, updates, customizations, integrations, and reporting \u2014 none of it can really be skipped. This guide walks through the main differences and what they mean for planning a move from AX.<\/p>\n\n\n\n

What Is the Difference Between Dynamics AX and Dynamics 365?<\/h2>\n\n\n\n

Microsoft\u2019s previous, on-premises ERP system was called Dynamics AX, and it was developed primarily for bigger organizations with large production, distribution, or business operations. It performed fine, but with a catch: you had to have a private server, your personal IT team, and sufficient time to manually update whenever an issue required fixing or upgrading.<\/p>\n\n\n\n

Then came 2016, and Microsoft launched Dynamics 365, taking AX and its CRM<\/a> counterpart and rolling them into a single cloud-based platform. Rather than a huge rigid system, you now have distinct applications \u2013 Finance, Supply Chain<\/a>, Sales<\/a>, Customer Service \u2013 that communicate with one another seamlessly.<\/p>\n\n\n\n

The real differences come down to how it’s deployed (cloud vs. on-premises), how it updates (automatic vs. manual), and how it connects with tools like Power Platform and Office 365.<\/p>\n\n\n\n

Dynamics AX vs Dynamics 365: At a Glance<\/h2>\n\n\n\n

Dynamics 365<\/a> is not a single application, but a group of applications, so what you receive depends upon which one you are working with. This comparison compares AX 2012 to the most appropriate Dynamics 365 options for AX users. Updates and custom code refer primarily to Finance and Supply Chain Management.<\/p>\n\n\n\n

Key Differences Between Dynamics AX and Dynamics 365<\/h2>\n\n\n\n

The two platforms differ most in how they’re built, updated, and used day to day. Here’s a closer look at where they diverge \u2014 from infrastructure and upgrades to customization<\/a> and analytics.<\/p>\n\n\n\n
