Cloud Migration Consulting · Sydney, NSW
Move your systems to the cloud without moving your team into six months of disruption.
Your on-premises servers are ageing, expensive to maintain, and limiting what your business can do. But migration projects have a reputation for blowing budgets and timelines. Human Nexus delivers cloud migrations with fixed scope, fixed price, and a plan that keeps your operations running throughout.

The problems we fix.
Ageing on-premises infrastructure is a growing risk
End-of-life hardware, unsupported operating systems, and rising maintenance costs. Every month on-premises is a month of increasing operational and security risk.
Migration projects are notorious for scope creep
What starts as a lift-and-shift becomes a full re-architecture with no clear end date. We scope the migration upfront, price it fixed, and keep the project bounded.
Your team cannot afford downtime during migration
Care providers, financial services, and operational businesses cannot tolerate system outages. We design migration strategies with cutover windows measured in minutes, not days.
How we deliver it.
01
Infrastructure audit
We catalogue every server, database, and application in your current environment. Dependencies mapped. Security and compliance requirements documented. Migration viability assessed per workload.
02
Migration strategy
Per-workload decision: lift-and-shift, re-platform, or rebuild. Cost modelling for each approach. Migration sequencing to minimise operational disruption. Fixed-price quote delivered.
03
Execute and validate
Phased migration with parallel environments. Automated testing against production data. Performance validation before cutover. Rollback plan for every workload.
04
Cutover and optimise
Scheduled cutover with minimal downtime. Post-migration monitoring for 30 days. Cost optimisation: right-sizing, reserved instances, auto-scaling configuration.
What's included.
Lift-and-shift migration
Move existing workloads to cloud VMs with minimal changes. Fastest path to cloud. Reduces hardware risk immediately while you plan longer-term modernisation.
Re-platform migration
Move to managed cloud services: RDS instead of self-managed SQL Server, ECS/EKS instead of on-prem VMs, S3 instead of file servers. Better scalability and lower ops burden without full rebuild.
Cloud-native rebuild
Rebuild applications for cloud-native architecture: serverless (Lambda, Cloud Functions), containerised (Docker, Kubernetes), and event-driven. Maximum scalability and cost efficiency.
Database migration
SQL Server to RDS/Aurora, Oracle to PostgreSQL, on-prem MongoDB to Atlas or DocumentDB. Schema conversion, data migration with CDC (change data capture), and cutover with minimal downtime.
Security and compliance migration
Identity migration to Entra ID/AWS IAM, network security group design, encryption at rest and in transit, compliance mapping (ISO 27001, APPs, ASD Essential Eight).
Hybrid and multi-cloud architecture
Not everything belongs in one cloud. We design hybrid architectures that keep sensitive data on-premises or in Australian regions while leveraging cloud for scalability and resilience.
Why Human Nexus.
Fixed price, defined scope
Every migration scoped per workload. Fixed price. No open-ended billing. If scope changes mid-project, we price the change before doing the work.
Zero-downtime migration design
We design cutover strategies measured in minutes, not days. Parallel environments, automated data sync, and tested rollback plans for every workload.
Australian data residency
All cloud infrastructure deployed in Sydney (ap-southeast-2) or Australian Azure regions by default. Data never leaves Australian jurisdiction unless you explicitly require it.
Cost transparency from day one
We model your cloud operating costs before migration begins. Reserved instance planning, auto-scaling configuration, and budget alerts set up as part of the migration, not an afterthought.
Your team owns the cloud environment
All infrastructure deployed in your cloud accounts. Full administrative access. Infrastructure-as-Code (Terraform, CloudFormation, Bicep) handed over so your team can manage and extend.
Australian project management
Sydney-based project lead manages the migration. Direct line to the team doing the work. No offshore handoffs at critical cutover moments.
Proof of work
300+ automation processes migrated and modernised for a national care provider.
Human Nexus migrated critical back-office automation from on-premises SharePoint and file-based workflows to cloud-native Power Platform and Azure services, eliminating hardware dependency and enabling real-time data integration across four operational systems.
$430K per fortnight in operational savings.
Common questions.
How much does cloud migration cost?
Small single-server migrations start from $8,000 to $15,000. Mid-range multi-server migrations range from $25,000 to $60,000. Large enterprise migrations with hundreds of workloads range from $80,000 to $250,000. Fixed-price quotes after a free infrastructure audit.
How long does cloud migration take?
Simple lift-and-shift: two to four weeks per workload. Re-platform: four to eight weeks. Cloud-native rebuild: eight to sixteen weeks. We phase migrations so critical systems move first and you see value within the first month.
Which cloud provider do you recommend?
We are cloud-agnostic and recommend based on your requirements. AWS for broadest service range and largest Australian presence. Azure for Microsoft-heavy environments and Entra ID integration. GCP for data and analytics workloads. We advise during the infrastructure audit, not before understanding your environment.
Will there be downtime during the migration?
We design for minimal downtime. Most cutovers complete within a scheduled maintenance window of 15 to 60 minutes. Critical systems use blue-green deployment with near-zero downtime. Every workload has a tested rollback plan.
How do you handle data security during migration?
Data in transit is encrypted via TLS 1.3 or VPN. Data at rest is AES-256 encrypted. Access is least-privilege and time-bound. All migration activity is logged and auditable. Australian Privacy Principles compliance maintained throughout.
What about ongoing cloud costs after migration?
We model your monthly cloud operating costs before migration begins and set up budget alerts. We configure auto-scaling and reserved instances to optimise cost. You receive a post-migration cost report at 30, 60, and 90 days with recommendations for further optimisation.
