Cloud migration testing
Cloud migration testing checks that your applications, data and infrastructure work correctly after the move to the cloud. We test before, during and after migration: data integrity, performance against your baseline, security and functionality.
What we check
- DataNothing lost or corrupted
- PerformanceAgainst the pre-migration baseline
- SecurityAccess, encryption, network
- FunctionalityEvery workflow, end to end
What is cloud migration testing?
Cloud migration testing is the validation that applications, databases and infrastructure components work correctly after moving from on-premises environments to cloud platforms.
It covers data integrity, application functionality, performance against a baseline and security compliance, through every phase of the migration.
Migration testing phases
A cloud migration testing approach in three phases. The baseline taken before the move is what every later result is compared against.
| Phase | Validation focus | Deliverable |
|---|---|---|
| Pre-migration | Baseline performance metrics, dependency mapping, data inventory and a compatibility check against the target cloud environment. | Readiness report |
| During migration | Data transfer validation, incremental sync checks, rollback procedure testing and downtime monitoring. | Migration log |
| Post-migration | End-to-end functional testing, performance compared with the baseline, security validation and user acceptance testing. | Validation report |
Testing types
Data validation
Confirm the data arrived complete and accurate, with nothing lost or corrupted.
- Record count verification
- Checksum comparison
- Referential integrity checks
- Data type mapping validation
Performance testing
Measure the application against its pre-migration baseline.
- Response time benchmarking
- Throughput measurement
- Resource utilization analysis
- Scalability validation
Security testing
Check security configuration and compliance requirements in the cloud environment.
- Access control verification
- Encryption validation
- Network security testing
- Compliance audit against your requirements
Functionality testing
Check the application features work in the new environment.
- End-to-end workflow testing
- Integration point validation
- API functionality checks
- User acceptance testing

Performance against the baseline is covered in depth on our performance testing page.
How BetterQA does cloud migration testing
We take the baseline before anything moves, test each migration wave as it lands, and test the rollback procedure while the old environment is still there to fall back on.
Engineers who test for a living
50+ QA engineers, working since 2018. People plan and run the cloud migration testing and report what the results mean for your release.
Bugs you can act on
Every defect we find is written up in BugBoard, our own test management tool, or in your tracker, with steps to reproduce, the expected and actual result, and the environment.
A certified process
ISO 9001 for quality management and ISO 27001:2022 for information security. See our certifications.

Cloud migration testing: common questions
What is cloud migration testing?
Testing that applications, data and infrastructure work correctly after moving from on-premises to a cloud platform: data integrity, functionality, performance and security.
How do you test and validate a cloud migration?
Take a baseline before the move, validate data and sync during it, and after it run end-to-end, performance, security and acceptance tests against that baseline.
What is cloud data migration testing?
Checking that data arrived complete and unchanged, with record counts, checksums, referential integrity checks and data type mapping.
Why test performance after a cloud migration?
The same application can behave differently on new infrastructure. Comparing with the pre-migration baseline shows whether response times and throughput held.
Which cloud platforms do you test on?
AWS, Microsoft Azure and Google Cloud Platform.
What does it cost?
Our rate is €20-45 per hour. For ongoing work the first month is a trial, the first two weeks are complimentary if you are not happy, and after that it is 30 days' notice.
Is cloud migration testing a kind of maintenance testing?
Yes. ISTQB CTFL 2.3 lists an upgrade or migration of the operational environment, such as a move from one platform to another, as a trigger for maintenance testing. It calls for tests of the new environment, tests of the changed software, and tests of data conversion where data from another application is migrated in. A common data check is to compare record counts and values before and after the move.
