Critical Infrastructure Changes: Plan Your Microsoft End-of-Life Migrations

November 3, 2025

If your organisation relies on Exchange Server, SQL Server 2016, SharePoint Server, or specific Azure services, critical end-of-life dates are approaching. These aren't just calendar dates—they represent significant milestones affecting your security, compliance, and operations.

What's Ending and When


Exchange Server 2016/2019: Support ended 14th October 2025. Immediate action required.


SQL Server 2016: Extended support ends 14th July 2026. All editions affected.


SharePoint & Project Server 2016/2019: Extended support ends 14th July 2026.


Azure Services: Anomaly Detector, API for FHIR, FXT Edge Filer, and Metrics Advisor retiring September-October 2026.



The Risks of Inaction

Operating unsupported systems exposes you to security vulnerabilities that will never be patched, compliance risks as many frameworks require current security updates, and integration challenges as modern applications phase out compatibility. For Exchange Server users, this risk exists right now.



Your Migration Options

We offer comprehensive migration services across all affected platforms:


• Exchange: Microsoft 365, hybrid deployments, or alternative platforms


• SQL Server: SQL Server 2022, Azure SQL Database, Azure SQL Managed Instance, or SQL Server on Azure VMs


• SharePoint: SharePoint Online, Microsoft 365, or hybrid solutions


• Project Server: Project for the Web, Project Online, or Microsoft Planner


• Azure Services: Migration to replacement Azure services or alternative cloud platforms




How We Help

We begin with a comprehensive assessment of your environment, identifying all affected systems and dependencies. Our team develops a prioritised migration roadmap aligned with your business needs, budget, and timeline.


We manage the entire technical implementation—from planning and testing through to cutover and post-migration support—ensuring minimal disruption to your operations.
