Azure Migrate Service

  • Free tool for primarily IaaS-based assessments.
  • Good for lift-and-shift migrations.
  • Supports VMware-virtualized Windows and Linux VMs.
  • Non-intrusive discovery of on-premises VMs & workloads
  • Examines & assets:
    • Azure readiness
      • Suitability of on-premises machines
      • Asserts • ready for azure, • ready with conditions, • not ready for Azure, • Azure readiness unknown (when readiness cannot be identified due to data unavailability)
    • Sizing suggestions
      • For VMs & disks based on history
      • Two settings:
        • As on-premises
        • Performance based
          • Based on utilization history
            • Storage: default is Premium disks
            • Network: performance required by network adapters
            • Compute: CPU & memory requirements
    • Cost estimation
      • The estimated cost for running the machines & storages in Azure
    • High confidence migration
      • Migration risks and recommended tools: recommends e.g. Azure Site Recovery
      • Visualize dependencies of on-premises machines through dependency maps
      • Create groups that you will asses and migrate together
  • Assessment content
    • Target location, Storage type, Reserved Instances, Sizing criterion, Performance history, Comfort factor, VM series, Currency, Discount (%), VM uptime, Azure offer, Azure Hybrid Benefit
      • Comfort factor: Buffer that's applied on top of machine utilization data for VMs.
  • ❗ Assesses only VMWare (>5.5) environments, for Hyper-V machines use Azure Site Recovery Deployment Planner.

Flow

  1. Create migration project
    • In Azure, create an Azure Migrate project.
  2. Install Collector
    • You download .OVA & import in VMware vCenter as VM
    • Read-only VM to log
  3. Configure Collector
    • You connect to console of VM or web to initiate the discovery
    • Copy & paste your project id and key from Azure.
    • It reads: config data, virtual processors, memory size, disk, network configuration, performance history (CPU utilization, memory, disk IOPS & throughput, network output to choose right size for VMs)
  4. Select VMs or groups (can customize groups) & create assessment.
    • Customize machines in report to recalculate costs.
  5. You can optionally install Dependency Agent to see dependency maps
