A software engineering team intends to relocate a popular application from an on-site data center to an external environment. The team plans to keep the operating system and overall architecture unchanged to avoid major code alterations. Which migration approach best fits these requirements?
Retain
Rehost
Replatform
Refactor
Rehost involves transferring an application into a new environment with minimal code changes, matching the team’s requirement of retaining the existing setup. Replatform requires moderate modifications, and Refactor requires deeper rewrites. Retain means leaving the application in its original location, which is not the team’s plan in this situation.
