Cloud migration planning: Incorporating the 6Rs and 7Rs for success

In today’s digital environment, cloud adoption has become essential for organisations aiming to improve security, scalability, and operational flexibility. However, success depends on clear and structured cloud migration planning. Using proven frameworks such as the 6R cloud migration strategy and the 7R in cloud migration planning helps organisations move workloads with clarity, control, and measurable business value. 

What is cloud migration planning?

Cloud migration planning is a structured process used to evaluate an organisation’s existing applications, data, and infrastructure and decide how they should move from on-premises environments to the cloud. The objective of cloud migration planning is to align technical decisions with business goals such as cost optimisation, performance improvement, and long-term scalability. Proper planning reduces risk, avoids downtime, and ensures smoother adoption of cloud platforms.

Understanding the 6R cloud migration strategy

The 6R cloud migration strategy provides a clear framework for deciding how each application should be treated during migration.

• Rehost involves moving applications to the cloud with minimal changes when speed is the priority.

• Replatform allows small adjustments to benefit from cloud services without changing core functionality.

• Refactor focuses on redesigning applications to fully use cloud native capabilities.

• Repurchase replaces legacy systems with modern SaaS solutions.

• Retirement removes unused or low-value applications to reduce cost and complexity.

• Retain keeps certain applications on-premises due to compliance or technical constraints.

This framework forms the foundation of a strong cloud migration strategy.

The 7R framework in cloud migration planning

The 7R in cloud migration planning builds on the original model by adding Relocate. This option supports virtualised environments by enabling workloads such as VMware to move directly to cloud platforms without changing application code or architecture. Relocate is ideal for organisations that want speed and low risk while maintaining existing operating models.

Building a cloud migration project plan

A successful cloud migration project plan follows a clear and repeatable structure. This includes:

• Discovery and assessment help identify the right R for each workload.

• Infrastructure readiness ensures the network and security layers can support migration.

• Connectivity setup enables secure and fast access to cloud providers.

• Migration execution moves applications based on business priority and chosen strategy.

This approach ensures consistency and predictability across all migration phases.

Data centre migration to cloud: Key steps and considerations

A data centre migration to cloud project plan requires careful attention to performance, availability, and scalability.

• Low-latency connectivity is critical for business applications.

• Redundant network design ensures high availability and uptime.

• Scalable bandwidth allows organisations to respond quickly to changing demand.

These factors are essential to maintaining service quality during and after migration.

Developing a cloud data migration strategy

A well-defined cloud data migration strategy is critical to ensure that data moves to the cloud without risk of cost overruns or loss of control. It should balance financial efficiency, strong security and full visibility across environments so organisations can manage data with confidence throughout the migration journey.

Key elements of an effective cloud data migration strategy include

• Cost optimisation: Using private and dedicated connectivity instead of the public internet helps significantly reduce data transfer and egress costs while improving performance.

• Security: Zero Trust security models ensure that every user, device and connection is verified, protecting sensitive data during and after migration.

• Visibility and control: Enhanced visibility across cloud networks allows better monitoring, governance and troubleshooting across multi-cloud environments.

Together, these elements ensure that data is migrated safely, efficiently and in a cost-effective manner while maintaining full operational control.

Common challenges in cloud migration planning

Even with a well-planned cloud migration strategy, organisations often encounter practical challenges during execution. These issues can affect performance, cost control and overall migration timelines if not addressed early.

Common challenges in cloud migration include:

• Limited visibility: Difficulty in monitoring and managing traffic across multi-cloud environments can lead to operational complexity.

• Unpredictable performance: Dependence on the public internet often results in inconsistent application performance and user experience.

• Rising data egress costs: Outbound data charges from cloud providers can quickly increase overall migration and operational costs.

• Slow provisioning: Traditional network and connectivity models often involve long lead times, which delay cloud adoption and scaling.

Best practices for a successful cloud migration strategy

To ensure a smooth and efficient transition to the cloud, organisations must follow proven best practices that reduce risk, improve performance and maximise long-term value. A structured approach helps turn cloud adoption into a sustainable and scalable cloud migration strategy.

Best practices for a successful cloud migration include:

• Prioritise workloads early:  Identify which applications should be migrated, retired or modernised to reduce complexity and focus on high-value systems.

• Choose private and dedicated connectivity: Move beyond public internet access and traditional VPNs to ensure secure, reliable and consistent cloud performance.

• Use automation: Implement automated orchestration to minimise manual effort, accelerate deployment, and reduce operational errors

• Monitor performance and cost continuously: Track network usage, application performance and cloud spend regularly to optimise efficiency and control costs

Final thoughts on using the 6Rs and 7Rs in cloud migration

The 6R cloud migration strategy and 7Rs in cloud migration planning together provide a clear roadmap for successful transformation. When combined with the right connectivity and execution model, they help organisations achieve agility, cost control, and long-term scalability. A well-defined cloud migration planning approach turns cloud adoption into a strategic advantage.
