Moving to AWS Cloud? A Readiness Checklist Before You Start
Manav Patel
Moving to AWS cloud is not only an infrastructure decision. It is a business continuity, security, cost, and modernization decision.
Many companies begin AWS migration by asking, “Which servers should we move first?” A better question is, “Are we ready to move safely?”
Cloud migration readiness helps identify what should be migrated, what should be fixed first, what risks need to be controlled, and what business outcomes the migration should support.
AWS defines migration phases around assess, mobilize, and migrate and modernize. AIMDek’s migration approach also starts with readiness, including infrastructure, workloads, databases, dependencies, security controls, operating model, and business priorities.
Quick Answer: What Should You Check Before Moving to AWS?
Before moving to AWS cloud, assess:
- Application inventory
- Workload criticality
- Infrastructure dependencies
- Database migration needs
- Security and access controls
- Backup and disaster recovery
- Compliance requirements
- Cost and licensing impact
- Migration wave sequencing
- Testing, cutover, and rollback readiness
- Post-migration operating model
This checklist helps reduce surprises before migration starts.
1. Business Readiness Checklist
AWS migration should be connected to business goals.
Ask:
- Why are we moving to AWS?
- Are we trying to reduce data center dependency?
- Do we need better scalability?
- Are we improving disaster recovery?
- Are we preparing for modernization?
- Do we need faster provisioning and releases?
- Are there upcoming hardware refresh costs?
- Which systems are business-critical?
- What downtime is acceptable?
If the business outcome is unclear, the migration roadmap will also be unclear.
2. Application Readiness Checklist
Applications should be reviewed before migration.
Check:
- Application owner
- Business function
- User groups
- Technology stack
- Current hosting environment
- Dependencies
- Integration points
- Performance requirements
- Release frequency
- Known technical debt
- Support status
- Migration complexity
This helps determine whether each application should be rehosted, replatformed, modernized, retained, or retired.
3. Infrastructure Readiness Checklist
Infrastructure readiness focuses on the current servers, virtual machines, storage, network, and operating environment.
Check:
- Physical servers
- Virtual machines
- CPU, memory, and storage usage
- Operating systems
- Network dependencies
- Firewall rules
- Load balancers
- DNS dependencies
- Backup systems
- Monitoring tools
- Patch management
- Environment separation
Do not assume current infrastructure sizing should be copied exactly into AWS. Migration is an opportunity to right-size and redesign where needed.
4. Database and Data Readiness Checklist
Database migration can be one of the riskiest parts of moving to AWS cloud.
Check:
- Database engines and versions
- Data volume
- Schema complexity
- Stored procedures
- Replication needs
- Downtime tolerance
- Data validation requirements
- Backup and restore process
- Application-database dependencies
- Reporting and analytics dependencies
- Compliance or retention requirements
AWS Database Migration Service supports migration and ongoing replication for relational databases, data warehouses, NoSQL databases, and other data stores.
Still, tools do not replace planning. Data integrity, validation, and cutover planning remain critical.
5. Security and Governance Readiness Checklist
Security should be planned before migration, not added later.
Check:
- Identity and access management
- Role-based access controls
- Network segmentation
- Encryption requirements
- Secrets management
- Logging
- Monitoring
- Vulnerability management
- Compliance requirements
- Incident response process
- Backup and disaster recovery policy
- Governance ownership
A secure AWS foundation helps avoid uncontrolled cloud sprawl after migration.
6. Cost Readiness Checklist
Cloud cost should be modelled, not assumed.
Check:
- Current data center cost
- Hardware refresh cost
- Licensing cost
- Support cost
- Backup and DR cost
- Staffing effort
- Current utilization
- Future AWS cost estimate
- Cost tagging model
- Budget alerts
- Optimization opportunities
AWS Cloud Economics describes cloud value across cost savings, staff productivity, operational resilience, business agility, and sustainability.
That means the business case should include cost, but not only cost.
7. Migration Execution Readiness Checklist
Before moving workloads, define how execution will be controlled.
Check:
- Migration wave plan
- Migration tools
- Test plan
- Cutover plan
- Rollback plan
- Communication plan
- Approval process
- Downtime window
- Success criteria
- Post-migration validation
- Hypercare support
For business-critical workloads, the migration plan should be reviewed by both technical and business stakeholders.
8. Operational Readiness Checklist
After migration, someone must operate the AWS environment.
Check:
- Monitoring ownership
- Alerting process
- Backup reviews
- Patch management
- Access reviews
- Cost reviews
- Security reviews
- Incident response
- Performance optimization
- Documentation
- DevOps automation roadmap
Without operational readiness, teams may move to AWS but continue working with old data center habits.

FAQs
What should I do before moving to AWS cloud?
Start with readiness assessment. Review applications, databases, infrastructure, dependencies, security, cost, operations, and migration risk.
Can all workloads move to AWS at once?
Usually no. Most organizations reduce risk by grouping workloads into migration waves based on dependency, complexity, and business criticality.
What is the biggest risk in moving to AWS cloud?
The biggest risk is poor planning. Missing dependencies, weak testing, unclear ownership, or lack of rollback planning can create disruption.
Should cost be the main reason to move to AWS?
Cost is important, but AWS migration should also consider scalability, resilience, security, agility, and modernization value.
