Migrating physical servers to Azure used to mean assessing them separately from your virtual machines — a gap that made mixed-environment planning harder than it needed to be. Azure Migrate now assesses physical servers alongside VMware and Hyper-V VMs in the same project, at a scale of up to 35,000 servers, so a business running a hybrid environment gets one unified migration plan instead of three disconnected ones.
Here’s what that assessment actually covers, and how to run it.
H2: Azure Suitability: Knowing What Can Move As-Is
Before committing to a migration timeline, the assessment checks each discovered server against Azure’s compatibility requirements and flags what can migrate as-is versus what needs remediation first — with specific guidance on fixing flagged issues, not just a pass/fail flag. Assessment properties are adjustable, so a business can rerun the analysis against a specific VM series or a defined workload uptime requirement rather than relying on default assumptions.
H2: Cost Estimation That’s Based on Actual Usage, Not Guesswork
A common migration mistake is sizing new cloud infrastructure to match on-premise specs exactly — which usually means migrating years of over-provisioning along with the workload. Performance-based rightsizing solves this by using real on-premise performance data to recommend the actual Azure VM and disk SKU a workload needs. Subscription offers and Reserved Instance pricing apply directly to these estimates, so the cost projection reflects what the migration will actually cost, not list price.
H2: Dependency Mapping Prevents the Migration That Breaks Something
The riskiest part of any multi-server migration isn’t moving the servers — it’s discovering after the fact that two “unrelated” systems were actually dependent on each other. Application dependency analysis maps which workloads need to migrate together, visualized as a dependency map or exported as tabular data for planning. This is what lets a migration be phased into groups deliberately, instead of guessing at what’s safe to move first.
H2: The Assessment Process in Four Steps
- Create an Azure Migrate project and add the Server Assessment solution to it.
- Set up the Azure Migrate appliance and start server discovery using server names or IP addresses. Each appliance covers up to 250 servers — deploy multiple appliances for larger environments.
- Run the assessment and review the reports — suitability, cost, and sizing all populate together.
- Use dependency analysis to build and refine migration groups, phasing the rollout based on actual interdependencies rather than assumptions.
H2: What Happens After the Assessment
Assessment answers the planning questions — what’s compatible, what it will cost, what needs to move together. Actually executing the migration is a separate step, using Azure Migrate’s Server Migration tooling once the assessment and grouping are complete.
