Cloud Migration Services: A Buyer’s Guide for Australian Businesses

Global cloud spending is set to reach $878 billion in 2026, according to Gartner’s latest forecast. In Australia alone, 86% of businesses now use cloud services, up from just 42% in 2018. The shift is undeniable.

Yet here’s what the marketing materials don’t tell you: up to 70% of cloud migration projects fail or stall. Not because the technology doesn’t work, but because businesses underestimate what’s involved in getting there.

This guide covers what cloud migration services actually deliver, what they cost, how long they take, and how to choose a provider that won’t leave you stranded mid-project.

Cloud migration services help businesses move their IT infrastructure, applications, and data from on-premises systems (or older cloud environments) to modern cloud platforms like Microsoft Azure, Amazon Web Services (AWS), or Google Cloud.

A migration provider handles the technical complexity so your team can focus on running the business. This typically includes assessing your current environment, planning the migration sequence, executing the move, optimising performance, and providing ongoing support.

The scope varies significantly. Some projects involve moving a few email accounts to Microsoft 365. Others require relocating entire data centres with hundreds of applications and petabytes of data. WellSpan Health, for example, is migrating 7.5 petabytes of clinical data and over 300 applications to AWS, a project spanning multiple years.

The distinction between DIY migration and managed services matters. Internal IT teams can handle straightforward moves, but complex environments with legacy systems, compliance requirements, or tight downtime windows typically need specialist expertise. The difference often shows up in the failure statistics.

Australian organisations are accelerating cloud adoption for several interconnected reasons.

Not every application needs the same treatment. The industry has settled on six primary migration strategies, commonly called the “6 Rs.”

Migration costs vary dramatically based on complexity, but here are realistic ranges for Australian businesses.

For small to medium businesses, typical Azure migrations cost between $5,000 and $40,000. This covers lift-and-shift projects involving 5-20 virtual machines and straightforward data transfers. A more comprehensive engagement covering assessment, planning, execution, and training typically runs $10,000-$25,000.

Enterprise migrations involving hundreds of applications, complex integrations, and refactoring work can exceed $500,000. These projects often span multiple years and require dedicated migration teams.

Beyond the migration itself, budget for these commonly overlooked costs:

Timeline expectations should match project complexity.

Average enterprise migrations now take around 8 months, down from 12 months in 2019 as tooling and methodologies have matured. However, this average masks significant variation.

Several factors accelerate or delay timelines:

Choosing the right partner often determines whether your migration succeeds or joins the 70% that fail. Here’s what matters.

Understanding risks enables mitigation. These issues derail migrations most frequently.

Define success criteria before migration begins. These metrics matter most.

These questions reveal provider capability and fit.

Watch for these warning signs during evaluation:

Cloud migration has moved from competitive advantage to business necessity. 85% of businesses now pursue cloud-first strategies because the benefits, cost efficiency, scalability, security, and resilience, compound over time.

The question isn’t whether to migrate, but how to do it well. The 70% failure rate reflects poor planning and partner selection, not fundamental technology problems. Businesses that invest in thorough assessment, choose experienced partners, and maintain realistic expectations consistently achieve successful outcomes.

For Australian businesses evaluating cloud migration services, the checklist is straightforward: verify provider expertise through certifications and references, ensure local support presence, confirm security and compliance capabilities, and understand exactly what’s included in proposed pricing.

The cloud isn’t going anywhere. Neither are the businesses that migrate thoughtfully.
