Keeping your software up to date means you get continuous support and servicing, including security updates, bug fixes, new features, and applicable regulatory compliance updates.

Modern Lifecycle Policy – 365 Business Central

Introduced in October 2019, the Modern Lifecycle Policy applies to Microsoft Dynamics 365 Business Central 2019 version 15.x (Wave 2) onwards.

Microsoft will release two updates per year for Business Central. The Wave 1 release takes place in April and Wave 2 the following October.

The diagram below outlines the planned release dates for each version.


Business Ready Enhancement Plan (BREP) & Subscription

The Modern Lifecycle Policy covers products and services that are serviced and supported continuously. If you have an active BREP (Support) plan or pay by subscription, you’ll have access to the latest updates available.

Your Microsoft Partner will be able to advise on any additional costs to implement the updates.

Points to consider before upgrading

You don’t need to update every 12 months. For example; If you have Business Central version 15 Wave 2, unless version 16 Wave 1 has a feature you are waiting on – then you may want to hold off and work with your Support partner to determine what’s best for your business.

Read what’s new and planned for the 2020/21 releases in our recent blog: Overview of Dynamics 365 Business Central 2020 release wave 1.

Important: Microsoft Dynamics 365 Business Central Version 14 will be available to access until October 2020. After this date, version 15 will be the only available operating version of Microsoft Dynamics 365 Business Central.

Fixed Lifecycle Policy – Business Central v14

Dynamics 365 Business Central versions 14x (April 2019) and before followed the Fixed Lifecycle Policy.

The Fixed Lifecycle Policy was designed to take the guesswork out of determining the length of time Microsoft provides support and servicing for a product.

In most situations, Microsoft provides 5 years of Mainstream Support. If you are currently using Dynamics 365 Business Central on-premise V14 you will have access to the Mainstream Support until October 2023.

The Fixed Lifecycle Policy worked well for previous installations of Dynamics NAV and Business Central, as solutions were often purchased perpetually and organisations would use the same version for several years.


Fixed Lifecycle Policy – Dynamics NAV

Dynamics NAV follows the Fixed Lifecycle Policy. Many versions are now no longer covered by mainstream or extended support.



The table below outlines the NAV Mainstream Support end dates:

NAV version Lifecycle Start Date Mainstream Support End Date
NAV 2018



NAV 2017



NAV 2015



NAV 2013 R2



NAV 2013



NAV 2009 R2



NAV 2009 SP1



Benefits of Upgrading Business Central or Dynamics NAV

Sooner or later mainstream support will stop for the older version of Business Central v14 or Dynamics Navision. Using v15 or above means you will have access to ongoing updates.

If you have heavily customised NAV, then some of the new Business Central add-ins available from AppSource, or from your Support partner, may help improve efficiencies and reduce some operating costs.

The 2020 pandemic has led to the faster adoption of cloud software – meaning many businesses have now begun the upgrade journey to Business Central.

At Turnkey, we can support your upgrade journey – you would be amazed at how many old reports and modules you don’t use anymore!
