Table of Content

    Beginning January 9, 2024, Microsoft Dynamics SL 2018 will move from mainstream support to extended support until July 11, 2028. 

    With this transition, it’s essential for your clients to understand what this change entails and how to prepare. 

    Understanding the Differences in Support 

    As Dynamics SL 2018 enters Extended Support in January 2024, only security patches will be provided, no year-end updates after 2024 will be available. However, existing customers can still buy new users or modules during the extended support period. 

    Moving forward, Extended Support will include: 

    • Paid support options. 
    • Continued availability of security updates at no extra cost. 
    • No new feature requests or design change requests. 

    However, with the end of Mainstream Support, Dynamics SL 2018 clients should be aware that: 

    • Non-security updates will no longer be available. 
    • To receive ongoing support, updating to the latest Service Pack may be necessary. 
    • Microsoft emphasizes the importance of installing the latest security updates and product releases for enhanced security. 

    Additionally, in December 2023, the last round of updates will be provided before mainstream support ends.

    Migration Guidance 

    When Extended Support for Dynamics SL 2018 ends on July 11, 2028, options will be limited. Microsoft will offer the Extended Security Update Program for certain products, which provides security updates beyond the official support period.  

    To help facilitate a smooth transition, Microsoft has recommended Dynamics 365 Business Central, offering a new promotion, Bridge to the Cloud 2. This promotion provides a 40% discount for three years, along with dual access rights, allowing clients to continue using their on-premise system while taking advantage of the cloud-based solution.  

    Next Steps for Partners 

    Clients should consider the several risks associated with running End of Life software, some of which include security vulnerabilities, compliance issues, and operational inefficiencies. These can cause several drawbacks for businesses if not addressed properly.  

    Moving forward, you’ll want to ensure that you’re following the latest updates regarding this lifecycle. Ultimately to prepare your clients, the focus should be on assessing the gaps in the proposed solutions and how best to fill those gaps to set your clients up for success.
