Hello Azure Community,
If high availability is a core part of your architecture strategy, there’s a new feature in public preview you should take note of — Azure Migrate now supports migration to Zone-Redundant Storage (ZRS) disks.
This enhancement means that during your migration journey, you can now directly target ZRS-enabled Premium SSD or Standard SSD disks for workloads that require zone-level resiliency. And the best part? Azure Migrate takes care of mapping and migrating eligible disks in supported regions.
Why This Is a Big Deal
ZRS disks replicate data synchronously across three physically isolated zones within the same region. Each zone has its own power, cooling, and networking — so even if one zone goes down, your storage layer remains available.
Here’s the real benefit: in the event of a zonal failure, ZRS disks can be force-detached from the impacted VM and reattached to another VM, enabling workload continuity without data loss or long recovery procedures.
This aligns perfectly with mission-critical systems where resiliency is not optional — think finance, healthcare, e-commerce platforms, or any customer-facing apps that can’t afford extended downtime.
From my perspective, this update pushes Azure Migrate even closer to being a comprehensive, enterprise-ready migration tool. You no longer need to perform post-migration reconfiguration just to get ZRS protection — it’s now built into the migration path.
If you’ve got an upcoming migration and resilience is on your checklist, it’s worth exploring this capability while it’s in preview.
See you soon,
Eduardo
