AWS Migration Readiness Assessment (MRA): What It Is and How to Run One

An AWS Migration Readiness Assessment (MRA) is a structured review of how prepared an organization is to move workloads to AWS. It finds strengths and gaps before migration work starts, and it ends with an action plan to close those gaps. AWS describes it as the assessment step of a migration, ahead of the mobilize and migrate phases.

Quick answer: run a readiness assessment before you commit to dates or budgets. Score your readiness across business, people, governance, platform, security and operations, list the gaps, and fix the critical ones before moving production data.

What an MRA is

AWS Prescriptive Guidance defines a migration readiness assessment as a process for learning how far along an organization is in its cloud journey, understanding its current strengths and weaknesses, and building an action plan to close the gaps. The AWS approach uses the AWS Cloud Adoption Framework (AWS CAF) and its six perspectives so the review covers more than servers and databases.

AWS expects three outcomes from a readiness review:

• An understanding of where the organization is in its cloud journey
• Identified strengths and weaknesses from a cloud-readiness point of view
• An action plan to resolve the gaps so migration does not stall to fix foundational problems later

Teams often also gain alignment between stakeholders and a shorter list of roadblocks.

The six perspectives

The AWS CAF perspectives are business, people, governance, platform, security and operations. The questions below are typical examples of what each one looks at. They are illustrative, not AWS's official question list.

Perspective	What it looks at	Example question
Business	Goals, business case, funding, executive sponsorship	Why are we migrating, and how will we know it worked?
People	Skills, roles, training, change management	Who will run this environment after cutover, and are they trained?
Governance	Program ownership, cost control, risk management, decision rights	Who approves cutover, and who watches spending?
Platform	Target architecture, landing zone, workload inventory, dependencies	Do we know every server, database and integration that must move?
Security	Identity, access, data protection, logging, compliance	Which data is sensitive, and how will it be protected in transit and at rest?
Operations	Monitoring, incident response, backup and recovery	If the migrated system fails at 2 a.m., who is alerted and what do they do?

What an assessment produces

The output is a picture of readiness by perspective and a prioritized list of gaps with owners. Some consultancies present this as a heatmap or radar chart, but the format matters less than the action list. A useful result names specific gaps, such as "no tested restore" or "no named owner for rollback decisions", instead of a generic score.

How to run one

1. Set the scope. Decide which workloads, teams and environments the assessment covers. A single application needs a lighter review than a data center exit.
2. Gather the right people. Include business, IT, security, operations and the application owners. Gaps often sit between teams.
3. Answer each perspective with evidence. "We have backups" is an opinion. "The last restore test succeeded on this date" is evidence.
4. Score honestly. Treat "not sure" as a gap, not a pass.
5. Rank the gaps. Put safeguards that could stop a migration or cause data loss first: inventory, tested backups, a rollback plan and operational readiness.
6. Turn gaps into an action plan with owners and dates, then reassess before scheduling cutover.

Enterprise MRA or a lighter check?

The AWS MRA framing is built for organizations planning migration at scale. If you are moving one application or a handful of servers, a full six-perspective program review may be more than you need. In that case the practical questions are narrower: do you have an inventory, a restore-tested backup, a data plan, a validation method, a cutover approach, a rollback plan and operational ownership?

CloudSyncPK's free migration readiness assessment is a lighter, workload-level check. It is ten questions across discovery, data, application, cutover and operations, and it flags four critical safeguards regardless of the overall score. It is a planning aid, not the official AWS MRA, and it does not replace a review of your actual environment.

What to do after the assessment

Fix the critical gaps first, then build the migration plan: workload inventory, approach per workload, migration waves, data validation, cutover runbook and rollback triggers. The AWS migration checklist walks through those preparation steps in order. Confirm that recovery is proven before any move by reviewing AWS backup best practices.

If you would rather have the assessment and plan done with you, the AWS cloud migration service covers discovery, migration waves, cutover and rollback planning.

The practical takeaway

A migration readiness assessment is cheap insurance. It turns "we think we are ready" into a list of evidenced strengths and named gaps before production data moves. Use the full AWS-style review for large programs and a focused workload check for smaller moves, and treat missing backups, rollback and operations as blockers either way.
