How long does cloud migration take?

Simple migrations (email, file storage) can be done in weeks. Full infrastructure migration for a mid-market business typically takes 3-12 months depending on complexity. Phased approaches are recommended: migrate low-risk applications first, build confidence, then tackle critical systems. Do not rush -- poor migrations cause more problems than they solve.

What should I migrate first?

Start with low-risk, non-critical applications to build experience and validate your approach. Good candidates: development environments, file storage, email (if not already SaaS). Then move to medium-criticality applications. Save mission-critical, complex applications for last when your team has cloud experience.

Do I need to migrate everything to the cloud?

No. Some systems may be better left on-premises due to latency requirements, regulatory constraints, or nearing end-of-life (retire instead). A hybrid approach is common and valid. Evaluate each application individually using the 7 Rs framework rather than mandating a one-size-fits-all approach.

Cloud Migration

Also known as:cloud transformationcloud adoptiondigital migration

The process of moving applications, data, and IT infrastructure from on-premises environments or legacy systems to cloud computing platforms.

In-Depth Explanation

Cloud migration is the process of transferring digital assets -- applications, data, databases, and IT resources -- from on-premises infrastructure or legacy hosting to cloud computing environments. It requires careful planning to minimise disruption and maximise cloud benefits.

Migration strategies (the 7 Rs):

Rehost (lift and shift): Move to cloud with minimal changes (fastest)
Replatform: Minor optimisations during migration (e.g., switch to managed database)
Repurchase: Replace with a SaaS alternative (e.g., on-prem CRM to Salesforce)
Refactor: Re-architect for cloud-native capabilities (most effort, most benefit)
Retire: Decommission applications no longer needed
Retain: Keep on-premises (not everything needs to move)
Relocate: Move to a different cloud provider

Migration phases:

Assessment: Inventory applications, dependencies, and requirements
Planning: Define migration strategy per application, timeline, and resources
Proof of concept: Migrate a low-risk application first to validate approach
Migration: Execute migration in planned waves
Optimisation: Tune for performance and cost in the cloud
Modernisation: Progressively adopt cloud-native features

Migration risks and mitigations:

Downtime: Plan migration windows, use parallel running, implement rollback plans
Data loss: Multiple backups, data validation, phased data migration
Performance issues: Load testing, right-sizing, monitoring
Cost overruns: Detailed cost modelling, regular reviews, reserved instances
Security gaps: Security assessment, compliance verification, access controls
Skill gaps: Training, partnerships, managed services

Business Context

Cloud migration typically delivers 20-40% reduction in IT costs over three years, but poor planning can lead to cost overruns and disruption -- the migration approach matters as much as the destination.

How Clever Ops Uses This

Clever Ops guides Australian businesses through cloud migration, from initial assessment through execution and optimisation. We evaluate each application for the best migration strategy, ensure data sovereignty compliance with Australian regions, and implement migrations in phased approaches that minimise business disruption.

Example Use Case

"An Australian manufacturing company migrates their ERP, CRM, and file servers to Azure over 6 months using a phased approach, reducing IT costs by 35% and gaining remote access capability that was critical during their expansion to regional offices."
