Understanding what are the 7 types of cloud migration begins with the 7 Rs framework: retire, retain, rehost, relocate, repurchase, replatform, and refactor or re-architect. These strategies help businesses decide what to move, what to replace, what to improve, and what to leave alone during a cloud migration.
For ecommerce teams, this framework matters because a migration is rarely just a technical move. Stores may depend on product data, customer records, orders, inventory, ERP systems, CRM tools, warehouse software, analytics, marketing platforms, and custom workflows. Choosing the wrong migration path can create cost, downtime, data problems, and operational confusion.
What Are the 7 Types of Cloud Migration? Start With the 7 Rs
The 7 Rs framework gives technical teams a structured methodology to classify every workload before making changes. For engineering leads assessing what are the 7 types of cloud migration, the value lies in applying these options to categorize applications based on operational complexity and technical risk. One system may need a simple move. Another may need a full rebuild. Another may not need to move at all.
| Cloud Migration Type | Simple Meaning |
|---|---|
| Retire | Remove systems that are no longer needed |
| Retain | Keep systems where they are for now |
| Rehost | Move the system with minimal changes |
| Relocate | Move infrastructure to a cloud version of the same environment |
| Repurchase | Replace the system with a different product, often SaaS |
| Replatform | Move and make limited improvements |
| Refactor or re-architect | Redesign the system for stronger cloud performance |
For brands asking what are the 7 types of cloud migration, the key is not memorizing the names. The real value is using the framework to make better decisions before moving systems, data, or workflows.
A Shopify consulting review can help ecommerce teams decide whether migration issues come from the platform, the store architecture, the app stack, the data model, or the connected systems around the business.
1. Retire: Remove What the Business No Longer Needs
Retire means shutting down applications, tools, data sets, scripts, or workflows that no longer serve the business. This step often gets overlooked because teams focus on what needs to move.
For ecommerce brands, retirement can apply to old plugins, unused reports, duplicate apps, outdated product databases, inactive integrations, or legacy workflows that no team actually uses anymore.
Retiring unused systems can reduce cost, simplify migration, lower risk, and make the new setup cleaner. If a tool does not support current operations, moving it to the cloud may only preserve clutter.
2. Retain: Keep Some Systems in Place
Retain means leaving a system where it is for now. This can be the right decision when a system still works, has no urgent reason to move, has compliance concerns, or depends on a future phase of the migration.
Not every workload needs to move at the same time. For ecommerce teams, a legacy ERP, warehouse system, accounting platform, or internal reporting tool may stay in place while the storefront or customer-facing layer changes first.
Retain does not mean ignore. It means the team makes a deliberate decision to keep something stable until the business has a better reason or safer plan to change it.
3. Rehost: Move With Minimal Changes
Rehost is often called lift and shift. The business moves an application or workload to the cloud without changing much about how it works.
This can be useful when speed matters and the current system is stable enough to move as-is. It can also help companies leave old infrastructure without redesigning the entire application first.
For ecommerce teams, rehosting may apply to internal tools, reporting systems, middleware, or legacy applications that still support the business. However, rehosting does not solve poor architecture, messy data, or weak workflows. It mainly changes where the system runs.
4. Relocate: Move the Existing Environment
Relocate means moving infrastructure to a cloud version of the same or similar environment. It is often used when businesses want to move large groups of servers or workloads without redesigning each application individually.
This path can reduce disruption when the company uses an existing virtualized environment and wants a more direct infrastructure move. It is different from refactoring because the business is not rebuilding the application logic.
For ecommerce operations, relocation may fit backend systems that support the store but do not need immediate redesign. The team still needs testing because connected systems, network behavior, access rules, and performance can change after the move.
5. Repurchase: Replace With a Different Product
Repurchase means replacing an existing system with a different product, often a software-as-a-service platform. Instead of moving the old application, the business chooses a new tool that better fits current needs.
This can apply when an ecommerce company replaces a legacy platform, outdated CRM, old email tool, custom inventory system, or manual reporting process with a modern cloud-based solution.
Leveraging modern software as a service (SaaS) platforms allows ecommerce teams to replace legacy infrastructure with managed cloud solutions rather than maintaining custom codebases.
A structured Shopify migration process can support this kind of decision when a brand is replacing a legacy ecommerce platform with Shopify while also reviewing products, customers, orders, URLs, apps, and integrations.
6. Replatform: Move and Improve Carefully
Replatform means moving a workload while making selected improvements. The core system does not get fully rebuilt, but the team may improve hosting, database setup, integrations, performance, automation, or operational structure.
For ecommerce brands, replatforming may involve moving to Shopify, improving product data, rebuilding templates, replacing old apps, improving mobile experience, or connecting cleaner backend workflows.
The goal is controlled improvement. A replatform should not become an unplanned rebuild. Teams need to decide which improvements are worth making during migration and which changes should wait until after launch.
A Shopify website development project can help when migration includes storefront rebuilds, custom templates, API-connected features, and performance-ready Shopify architecture.
7. Refactor or Re-Architect: Redesign for the Cloud
Refactor or re-architect is the deepest migration strategy. It means changing how the application works so it can better use cloud capabilities, scale more effectively, improve performance, or support new business requirements.
This path may involve rewriting code, changing databases, redesigning integrations, separating services, improving automation, or rebuilding custom business logic.
For ecommerce teams, this may apply when the current system is too rigid for growth. Examples include complex B2B pricing, custom checkout logic, international storefront needs, advanced inventory flows, personalized product experiences, or deep ERP and CRM connections.
A custom Shopify API integration can help when the business needs custom data flows between Shopify and systems such as ERP, CRM, logistics, fulfillment, accounting, or internal operations.
How to Choose the Right Migration Type
Understanding what are the 7 types of cloud migration allows leadership to align infrastructure decisions with core business goals. Before choosing a path, teams should review the value, risk, cost, dependencies, and future role of each system.
Use these questions:
- Does the system still support the business?
- Can it be removed instead of moved?
- Does it need to stay stable for now?
- Can it move with minimal change?
- Would a new SaaS product solve the problem better?
- Does the system need only limited improvement?
- Does the business need a full redesign?
- What data, workflows, and integrations depend on it?
A cloud migration plan should classify workloads before implementation begins. Without that step, teams may waste time moving systems that should have been retired or rebuilding systems that only needed a smaller improvement.
Why Ecommerce Cloud Migration Needs Careful Planning
Ecommerce systems are connected. A change in one area can affect orders, inventory, product data, checkout, fulfillment, customer service, marketing, analytics, and reporting.
That is why what are the 7 types of cloud migration is not only a technical question. It is also an operations question. Each choice affects how the business will sell, fulfill, measure, and support customers after migration.
A good migration plan should protect:
- Product and variant data
- Customer records
- Order history
- Inventory rules
- Integrations
- SEO value
- Checkout behavior
- Reporting accuracy
- Staff workflows
- Customer experience
The goal is not to move everything at once. The goal is to move the right systems in the right way.
Aligning Migration Strategy With Long-Term Growth
Evaluating what are the 7 types of cloud migration-retire, retain, rehost, relocate, repurchase, replatform, and refactor-allows engineering leaders to choose the appropriate technical path for each workload.
For growing ecommerce brands, the ideal migration path depends on each system’s operational role. Certain tools require direct replacement, while others need architectural improvements or temporary retention. Partnering with Zissu Global provides Shopify merchants with the technical scoping, data mapping, and custom integration architecture required for seamless cloud transitions.
