Azure Migrate, Microsoft's cloud migration hub, gained a new capability in April 2026: automated, agentless discovery and assessment of SMB and NFS file shares hosted on Windows and Linux servers. The feature extends Azure Migrate's existing workload coverage — which already included servers, databases, and web apps — to file shares. It recommends which of Microsoft's two Azure Files storage tiers is appropriate for each share and estimates monthly costs. Previously, file share migration planning relied on manual scripts or spreadsheets. This article explains how the feature works, what you need to use it, and where its limitations lie.

Windows Server vNext Insider Preview build 29531 introduces ReFS boot, allowing you to install and start Windows Server from a Resilient File System (ReFS)-formatted boot volume for the first time. This feature brings integrity-level metadata checksums, online corruption repair, block cloning, and 35-petabyte volume scalability to the OS boot partition — capabilities that NTFS cannot match. ReFS boot requires UEFI firmware and a minimum of 2 GB for the WinRE partition. Learn how to enable Windows ReFS boot during Windows Server installation.
