Frequently asked questions
Costs vary hugely by scale, but a small-to-mid-sized UK business migrating a handful of servers and associated storage typically spends £5,000 to £25,000 on migration services, before ongoing monthly Azure consumption costs. Complex environments with legacy applications requiring re-architecting can push costs significantly higher.
Key drivers are the number of servers and applications being moved, whether applications need re-architecting for the cloud versus a straight lift-and-shift, data volume, and how much downtime the business can tolerate during cutover. Compliance requirements and staff training needs also add to overall migration cost.
Lift-and-shift is generally cheaper and faster upfront since applications move largely unchanged, but it often misses cost and performance benefits that come from redesigning workloads for cloud-native services. Many organisations start with lift-and-shift then re-architect specific high-value applications later once they are comfortable in Azure.
Beyond the one-off migration project cost, expect ongoing monthly charges for compute, storage, networking, and backup, which typically range from a few hundred to several thousand pounds a month depending on scale. This estimator breaks down both the upfront migration cost and the recurring Azure spend to expect.
