AWS migration assessment checklist: discovery through cutover

A structured checklist for inventory, dependencies, security, data, landing zones, testing, cutover, rollback, and post-migration operations.

Migration risk usually comes from unknown dependencies, unclear ownership, incomplete nonfunctional requirements, and weak cutover planning—not from copying compute resources into AWS.

01 · Analysis

Inventory applications and dependencies

Map services, data stores, integrations, DNS, certificates, identity, scheduled work, network paths, owners, criticality, and unsupported components.

02 · Analysis

Prepare the AWS foundation

Define accounts, identity, networking, logging, security controls, backups, observability, budgets, deployment, and access before production workloads arrive.

03 · Analysis

Choose a migration strategy per workload

Rehost, replatform, refactor, retain, retire, or replace based on business value, risk, time, technical debt, and operating goals.

04 · Analysis

Test cutover and rollback

Validate data consistency, performance, security, monitoring, recovery, DNS, communications, rollback triggers, ownership, and the post-cutover stabilization period.

Practical checkpoint

Before acting, confirm the owner, evidence, production risk, expected outcome, and validation method for each recommendation.
