What's the biggest cause of AWS migration failure?

Weak discovery and unmapped dependencies. A surprising integration, unsupported service or shared database often surfaces at the worst possible time — during cutover — when there isn't time to react safely.

How do you reduce downtime risk?

Through dependency mapping, test migrations, replication, phased cutover, defined rollback routes, monitoring before go-live, and a tested communication plan for each migration wave.

Do you produce a risk register?

Yes. A migration risk register captures each risk, likely impact, owner and mitigation — so the team has a shared view of what could go wrong and what's being done about it.

Risk Management

Move to AWS with less risk, less uncertainty and fewer surprises.

AWS migration risk management helps identify what could go wrong before production workloads move. IG CloudOps reviews downtime, data, security, cost, networking, dependencies and operational readiness.

Common AWS migration risks

Application downtime

Poor cutover planning can lead to extended outages or customer disruption.

Data migration failure

Databases, storage and replication need careful validation before final cutover.

Hidden dependencies

Unmapped services, integrations or manual processes can break after migration.

Security misconfiguration

IAM, network access, encryption and logging must be designed before go-live.

Cost escalation

Workloads moved without sizing and optimisation can become expensive quickly.

Weak rollback planning

Every critical migration wave should have a realistic fallback route.

Operational gaps

Monitoring, alerting, backups, incident processes and support ownership must be ready.

Sample migration risk register

Risk	Impact	Mitigation
Unknown application dependency	Failed cutover	Dependency mapping & test migration
Database replication issue	Data loss or downtime	Replication testing & restore validation
Poor IAM design	Security exposure	Least-privilege access review
Overbuilt AWS environment	Higher cost	Sizing & cost review
No rollback route	Extended outage	Defined rollback plan per wave
Weak monitoring	Slow incident response	Monitoring & alerting before go-live
