Rehost

Migration strategy that moves applications to the cloud without modification, commonly called lift and shift.

Definition

Rehosting copies servers as-is to cloud VMs, often with automated tools such as AWS Application Migration Service, Azure Migrate or Google Migrate to Virtual Machines. It is the fastest way to exit a data center and lets teams optimize later, but captures fewer cloud-native benefits.

Example

300 on-premises VMs are replicated to EC2 with MGN and cut over in weekend waves to meet a data center lease deadline.

Exam tip

Tight deadline and no code changes point to rehost (lift and shift).
