If you’re running your business on Microsoft Dynamics AX 2009 or 2012, you are no doubt aware that both software products are approaching the end of their life-cycles. Microsoft is ending Mainstream Support for Dynamics AX 2009, Dynamics AX 2012, and AX 2012 R2 this year and for AX 2012 R3 in 2021. That means no more security updates, hotfixes, warranty claims, design changes, features requests, and self-service support. You can purchase extended support. But be aware that extended support for AX 2009, AX 2012, and AX 2012 R2 ends in 2021. For AX 2012 R3, it will be available until 2023.
