Introduction
Cloud migration is no longer optional—it’s the foundation of digital transformation for modern enterprises. From mobile application development services to ERP development services, organizations rely on scalable and secure cloud solutions to innovate faster. But moving to the cloud requires a well-planned strategy. That’s where the 7 Rs of cloud migration strategies come in.
These strategies help businesses, like software development and DevOps companies, as well as enterprises. They explore AI and ML development solutions. These strategies find the best ways to modernize applications, cut costs, and boost efficiency.
In this guide, we will look at each migration strategy closely. We will highlight use cases and explain how businesses can make smart choices. This will help them get the most value from their cloud investment.
1. Rehost (Lift and Shift)
Rehosting is the simplest way to migrate applications and data from on-premises to the cloud without modifying code.
Benefits
- Fastest transition with minimal disruption
- Cost savings by reducing physical infrastructure
- Improved disaster recovery and uptime
2. Replatform (Lift and Optimize)
Replatforming makes slight modifications to applications during migration to leverage cloud-native services like managed databases and auto-scaling.
Benefits
- Enhanced Performance: Takes advantage of cloud-based optimizations.
- Cost Savings: Reduces operational expenses by leveraging the platform as a service (PaaS) and managed services.
- Scalability: Supports auto-scaling and dynamic resource allocation.
Challenges
- Development Effort Required: Some application modifications are needed.
- Limited Optimization: This doesn’t provide full cloud-native benefits like refactoring.
Best Use Cases
- Businesses are looking to improve performance without extensive redevelopment.
- Applications that can benefit from cloud migration strategies like auto-scaling.
- Organizations are aiming for a gradual cloud adoption approach.

3. Refactor (Re-architect)
Overview
Refactoring, or re-architecting, is a cloud migration strategy that involves redeveloping applications to be fully cloud-native. This method enables businesses to leverage microservices, serverless computing, and software containers, ensuring greater agility and efficiency.
Benefits
- Optimized Performance: Maximizes cloud computing capabilities.
- Future-proofing: Highly scalable and resilient applications.
- Reduced Maintenance Costs: Less manual intervention required.
Challenges
- High Complexity: Requires significant code changes.
- Time-Consuming: Needs skilled developers and cloud architects.
4. Repurchase (Drop and Shop)
Overview
Repurchasing means switching to a cloud-based SaaS (Software as a Service) solution instead of modifying an existing application. Many businesses move their work to the cloud. They do this by using public cloud services like Salesforce for customer management or Workday for human resources.
Benefits
- Instant Upgrades: SaaS providers handle maintenance and updates.
- Lower IT Overhead: Reduces in-house infrastructure management.
- Predictable Costs: Subscription-based pricing simplifies budgeting.
Challenges
- Data Migration Complexity: Transferring data to a SaaS platform can be challenging.
- User Training Needed: Employees may need to adapt to a new system.
Best Use Cases
- Companies transitioning to SaaS-based applications (e.g., CRM, ERP).
- Organizations seeking low-maintenance software solutions.
- Businesses looking for a fast and cost-effective digital transformation.

5. Retire
Overview
Retiring applications involves removing outdated or redundant systems during the cloud migration process. This helps businesses cut unnecessary expenses and simplify IT infrastructure.
Benefits
- Cost Reduction: Eliminates maintenance costs of unused applications.
- Simplifies IT Environment: Reduces operational complexity.
6. Retain (Revisit Later)
Overview
Retention is for applications that must remain on-premises due to security and compliance regulations or technical constraints. Some organizations delay migration until better solutions emerge.
7. Relocate
Overview
Relocating involves moving entire data centers to the cloud without modifying applications. This strategy uses virtual machines (VMs) and container-based migration to transfer workloads to the cloud efficiently.
Conclusion
The 7 Rs of cloud migration strategies are Rehost, Re platform, Refactor, Repurchase, Retire, Retain, and Relocate. These strategies help businesses use cloud computing to its fullest.
Whether you’re an AI consulting company for enterprises, a SaaS development services provider, or a cloud consulting firm in Atlanta, the right migration approach can reduce costs, accelerate innovation, and future-proof applications.
By aligning cloud strategy with business goals, organizations can achieve secure and scalable digital transformation. This includes intelligent data integration, smart data processing with AI, and AI and ML development solutions.
