RiverMeadow vs. Azure Migrate

Feature/Aspect Azure Migrate OS Modernization RiverMeadow OS Modernization
Upgrade Capability (Microsoft OS) Upgrade up to two versions from the current OS version. Includes: Win2012, Win2012R2, Win2016 & Win2019 Modernize Windows Server 2003 (64bit) through Windows Server 2022, Windows 7 through to Windows 11.
Upgrade Capability (Non-Microsoft OS) Not Possible Modernize RHEL, CentOS, OEL 6.x through to 9.x.
Test Migration Provides a test migration feature to test OS upgrades in an isolated environment in Azure​​. Cloning workloads to target clones running in isolation for safe and predictive migration, with validation possible during regular business hours.
Migration Process Simultaneous upgrade and migration operations, reducing duplicate planning and downtime. (On-prem to Azure Only) Supports on-prem to on-prem, on-prem to cloud, or cloud-to-cloud transitions, with delta sync for source and target workloads leading up to the planned cutover event.
Isolated Environment Testing Provides an isolated environment for testing in Azure​. Target clones run in isolation, protected by cloud-native firewalling or private cloud network isolation for testing and validation before cutover.
Supported Environments VMware, Hyper-V, and Physical servers. RiverMeadow is a cloud-agnostic Workload Mobility Platform supporting migrations from ANY Source to: Azure/AVS, GCP/GCVE, AWS/VMC, vSphere, and OpenStack.
Prerequisites VM must have the capability of adding another data disk. Have 32 GB of free disk space on the OS disk, and use Windows Server Standard or Datacenter editions. En-US language servers only. For Windows-based OS Modernization, at least 25GB of free space is required on the System Volume (C:) for temporary folders created by the upgrade.
Source Appliance required Yes, it is a time-consuming effort to create on-prem resources, assign permissions, discover the environment, and initiate replication. No - agent deployed automatically in minutes from the RiverMeadow platform.
Warnings, failure detection, and remediation capabilities. Once a system is migrated successfully or not, it is removed from the source list. Failed upgrades result in a lift and shift migration. Failed upgrades can immediately be rectified and run again.
Custom Scripting Not specified Allows uploading and invoking custom scripts during migration to modify Operations stack and/or Security configurations on target machines.
Performance Metrics / Right-Sizing Not specified Provides agent-less and real-time source VM performance metrics and right-sizing recommendations as part of a migration to VCF, AVS, GCVE, or VMC.
Network Optimization Not specified Supports L2 or L3 migrations with features like retaining IP/MAC, modifying NICs and IP addressing, applying new MTU sizes for VXLAN and other 3rd party technologies, and applying firewalling or Security Groups.
Storage Right-sizing Not specified Resize target partitions as part of migration to reduce storage footprint in the cloud.
