Azure Migration Services

Timelines depend on the number of workloads, dependency complexity and how many applications are being modernized rather than rehosted. Discovery and assessment typically take a few weeks, because we want enough performance data to size targets accurately. A landing zone follows in parallel or immediately after. Migration waves then proceed on a regular cadence, often every two to four weeks. We publish the full wave plan early so you can align business calendars and change freezes.

We evaluate each application against the common options: rehost, replatform, refactor, rearchitect, replace with SaaS, or retire. The decision considers business criticality, technical debt, licensing, team skills and deadlines. Many organizations rehost most servers to meet a data center deadline, then modernize selected applications afterward. We document the rationale for every decision so it can be revisited when priorities change.

Servers are replicated continuously before cutover, so the final switch only needs to synchronize recent changes. For databases we use online migration methods where they are supported. We run test migrations in isolated networks, rehearse the runbook, agree a cutover window with business owners and define rollback criteria in advance. Hypercare follows each cutover so issues are resolved quickly.

There are two components: the migration effort and your future Azure consumption. Effort depends on workload count, complexity, testing needs and compliance requirements. Consumption depends on sizing, licensing and commitment choices. We model run costs with Azure Migrate business case data and the Azure Pricing Calculator, and identify options such as Azure Hybrid Benefit, reservations and savings plans. You receive both estimates before any migration begins.

Security is built into the landing zone before any workload moves: Entra ID roles, Azure Policy assignments, private networking, encryption, Defender for Cloud and centralized logging. Data in transit during replication is encrypted. For regulated workloads we map controls to your framework and document evidence. Each wave includes a security review, and nothing goes live without passing it.

Not necessarily. Combining a data center exit with deep modernization often slows both down. A common pattern is to rehost first to meet a deadline, then modernize applications that benefit most, for example moving databases to Azure SQL Managed Instance or web apps to App Service. We help you sequence these steps so the migration delivers value early and modernization follows a clear roadmap.
