AWS Application Migration Service (MGN)
Amazon Web Services
Free
Near-zero - continuous sync, minutes to cut over
Agent
Enterprise estates
Workload P2C V2C C2C
What it is good at
Continuous block-level replication from anything that runs the agent, unlimited non-disruptive test launches, and cutover measured in minutes. Source-agnostic, which makes it the strongest general P2C/V2C tool.
Where it falls down
Agent-based - you need admin access and an outbound path to the staging subnet on every server. AWS target only.
Capabilities
- Changed-block tracking / incremental sync
- Wave / batch orchestration
- Non-disruptive test migration
- Rollback / failback after cutover
- Encryption in flight
- API / CLI automation
- Network and IP mapping
Cost and licensing

- Indicative price
- Free for 90 days per source server; then about US$0.042 per server-hour
- Licence model
- The service is free for 2,160 hours (90 days) per source server, which covers a normal migration. After that it bills per server-hour. You always pay for the staging-area EBS volumes, snapshots, data transfer and the target EC2 instances.
