For many Australian businesses, moving to the cloud is no longer a question of if, but how. Cloud platforms offer flexibility, resilience and access to modern tools that support growth and remote work. However, achieving these benefits depends on more than simply transferring systems from on-premises environments to the cloud.
A successful transition requires a clear cloud migration strategy. One that aligns technology decisions with business objectives, manages risk and ensures security from the outset. At Lanter, we’ve delivered countless cloud migrations across organisations of all sizes.
While many projects share similar foundations, no two are ever the same. Often, small details uncovered during planning shape the approach needed for each migration.
What Is a Cloud Migration Strategy?
A cloud migration strategy is a structured plan for moving applications, data and systems from on-premises environments to the cloud. This often includes platforms such as Microsoft Azure, Microsoft 365 or Google Workspace.
Rather than focusing purely on technology, it considers business goals, performance requirements, security obligations and long-term costs. A well-designed strategy sets out what moves to the cloud and how teams migrate it. It also defines timelines and how teams manage ongoing operations.
Scalability, resilience and flexibility
With the right cloud migration strategy in place, businesses can scale resources as demand changes. They can also strengthen disaster recovery capabilities and support hybrid or remote work environments more effectively. Cloud platforms also provide access to modern collaboration tools without the burden of maintaining physical infrastructure.
Lanter explores many of these drivers in more detail in its guide on why businesses are moving to the cloud.
Why Businesses Are Moving to the Cloud
Cloud adoption continues to accelerate as organisations seek greater flexibility and efficiency.
Why having a defined strategy matters
Without a clear strategy, cloud migrations often lead to unexpected downtime, security gaps and rising expenses. In practice, around 90% of the success or failure of a migration project lies in the discovery and planning phase.
At Lanter, we invest significant time upfront to understand system dependencies, performance needs and potential risks. Our experience helps us identify the right details early. This allows us to address unknowns before they become costly issues during delivery.

The Core Elements of a Cloud Migration Strategy
A successful cloud migration strategy focuses on more than just technology.
Business objectives and workload assessment
Every cloud migration should begin with a clear understanding of what the business is trying to achieve. This includes reviewing existing applications and infrastructure, identifying dependencies between systems and determining which workloads will benefit most from the cloud.
Importantly, knowing when not to move certain systems is just as critical as knowing when to migrate. While the cloud is usually an excellent option, it is not always the right choice. In some cases, the return on investment or productivity gains are minimal or even non-existent. A strong strategy balances opportunity with commercial value.
Security, compliance and cost planning
Security must be built into the migration process from the beginning. This involves protecting sensitive data, managing access controls and ensuring compliance with industry regulations. Cost planning is equally important, as poorly optimised environments can quickly become expensive over time.
Lanter integrates security best practices throughout every migration, supported by our wider cyber security services.
The 6 Rs of Cloud Migration
Many organisations use the “6 Rs” framework to guide cloud migration decisions. Each approach reflects a different level of change depending on business needs and technical complexity.
Rehost
Rehosting, often called “lift and shift”, involves moving applications to the cloud with minimal changes. This approach is typically faster but may not take full advantage of cloud capabilities. For example, a business might move an existing server into an Azure cloud environment without redesigning the application.
Replatform
Replatforming introduces small changes during migration to improve performance or reduce costs while maintaining the core application structure. This could include updating a database service or adjusting storage to better suit cloud performance.
Refactor
Refactoring, or re-architecting, involves redesigning applications to fully leverage cloud-native services for scalability and efficiency. Businesses often use this approach for critical systems that require high performance, flexibility or future growth.
Repurchase
Repurchasing replaces legacy systems with cloud-based software solutions. Such as migrating from on-premises email servers to Microsoft 365 or moving to cloud-based accounting software.
Retire
Retiring focuses on de-commissioning outdated or unused systems that no longer deliver business value. This helps reduce complexity, risk and ongoing costs.
Retain
Retaining keeps certain workloads on-premises because of performance requirements, compliance needs or cost considerations. Businesses may keep some systems in-house where cloud benefits are limited. Not every workload belongs in the cloud. The most effective strategies carefully evaluate each system based on risk, benefit and long-term value.
Key Risks to Address Before Migrating to the Cloud
Understanding potential risks helps ensure a smoother and more secure cloud migration.
Downtime, data security and unexpected costs
Common challenges during cloud migration include service disruptions, data loss, security vulnerabilities and cost overruns. Compatibility issues between applications can also create performance problems if not identified early.
Businesses can significantly reduce these risks through detailed discovery and careful planning. Phased migration approaches allow teams to resolve issues before they impact operations.
A Practical Cloud Migration Roadmap
Successful cloud migrations follow a structured and practical roadmap.
Assess, plan, migrate and optimise
Most successful cloud migrations follow a structured roadmap. It begins with assessing current systems, risks and business goals. Teams then complete detailed planning around workloads, security and timelines. They carry out the migration in controlled phases to minimise disruption.
Finally, ongoing optimisation ensures performance, security and costs continue to improve after the move.
This practical approach helps organisations stay in control throughout the process. At the same time achieving long-term benefits from their cloud investment.
