Dynamics NAV has evolved in recent years and is now Dynamics 365 Business Central.


If you are still operating using Dynamics NAV then it is important that you consider where you are in terms of Microsoft’s support. Support with Microsoft can be broken down into two time periods – mainstream support and extended support, and where you are in your support timeline is dependant on which version of NAV you currently use.

Our table below summarises the support timelines.

Version Mainstream Support Extended Support
Dynamics NAV 2009 No longer available No longer available
Dynamics NAV 2015 No longer available 14th January 2025
Dynamics NAV 2016 No longer available 14th April 2026
Dynamics NAV 2017 No longer available 11th January 2027
Dynamics NAV 2018 No longer available 11th January 2028
What’s the implication of running NAV without mainstream support?

If you are no longer accessing Microsoft’s mainstream support then you are missing out on the latest features and enhancements within your Dynamics applications, effectively running a diluted, less productive system.

Once your mainstream support period ends, you’ll move to a five year period of extended support, meaning only security updates will be available and for a limited period.

When you reach extended support stage you should also be concerned with issues such as:

Limited security: Microsoft continually improve their security to fend off malicious threats and attacks. Unsupported NAV can leave your businesses open to hackers and other breaches.

Emergency Fixes: If you continually miss out on upgrades across your software packages then one minor system breakage can cause multiple impacts, leading to the need for costly and complex emergency fixes.

Lost productivity: Every new version brings improvements and enhancements that deliver productivity gains, running unsupported means you miss out on these gains.


What are my options?

Common Questions

In our experience, the risk of running an unsupported version of Dynamics NAV should be of immediate concern and a key driver behind upgrading to Dynamics Business Central.  Enhanced security, continually missing out on upgrades and lost productivity from running an outdated application are three of the key risks you need be considering.
