One Version

One Version is Microsoft's policy for Dynamics 365 Finance and Supply Chain Management: every production environment, in every region, on every tenant, runs the same current platform version, updated continuously via Service Updates roughly every six weeks. Customers cannot remain indefinitely on older versions. Limited pause windows allow deferring updates for a small number of cycles per year (typically around year-end), but mandatory upgrades apply after the pause expires. Microsoft maintains this policy because supporting hundreds of AX-era versions in SaaS would be economically infeasible. The discipline is real; the benefits — continuous improvements, security patches, no big-bang upgrade projects — accrue over time.
