A cloud migration strategy outlines the necessary steps to move your data and software to the cloud. It is important to identify problems, set clear goals, and thoroughly assess your current hardware and software to determine the best approach.
A poor migration plan can lead to issues like no performance gains, financial losses, or damage to your company’s reputation. For instance, migrating applications to the cloud while keeping outdated databases can undermine the benefits of the move.
To achieve a successful migration, it is crucial to address technical challenges, especially when transitioning traditional software to modern cloud setups such as multi-cloud environments, serverless computing, and containers.
Let’s take a look at the most popular cloud migration techniques before delving deeper into these issues.
Top 6 Cloud Migration Strategies

Let’s focus on three main migration scenarios and summarize other subtypes at the end.
Replatforming
Replatforming in cloud movement refers to a middle ground approach.
It is seen as offering a good price/performance balance, allowing businesses to utilize cloud benefits effectively. This method improves apps and data repositories by adjusting their code or usage.
For example, a database can be set up as a service and linked to the app, enhancing performance through native data transfer using cloud architecture.
Rehosting
Lift-and-shift migration techniques require minimal investment and effort. This strategy involves making small adjustments to databases and applications to enable their operation in the cloud. Rehosting is suitable for businesses starting their cloud transition, providing an introduction to cloud computing. However, since the data and applications aren’t tailored for cloud services, the full benefits of the move may not be realized.
Refactoring
Moving legacy software to the cloud can be challenging since it often wasn’t designed for that environment. This process usually requires redesigning the software, which is known as refactoring. Refactoring involves making significant changes to the code while keeping its functionality unchanged, and it demands prior software development experience. Although refactoring may take time, the end result is a well-functioning solution that doesn’t need ongoing support. The software can then leverage various cloud services effectively. It is advisable to hire a specialized team or to use your internal IT staff efficiently
Retire
A key strategy for decommissioning applications is the retirement migration strategy. Deciding to retire applications can be complex and risky. Organizations must fully understand all dependencies, especially if the application may be used elsewhere. A thorough assessment is essential for a successful retirement migration plan.
Retiring applications can be a smart choice for several reasons.
– First, if an application lacks business value, it is better to retire it to use resources efficiently.
-Second, retiring helps reduce costs and technical debt, allowing organizations to focus on more important projects.
Lastly, security is also prioritized in this decision.Reducing security risks should be a top priority, particularly for programs that depend on unsupported components or run on obsolete operating system (OS) versions. Retiring these apps protects the organization’s overall security posture by reducing potential vulnerabilities.
-Unmet performance metrics is also important for security. Keeping applications that don’t meet performance standards helps avoid problems and keeps the organization efficient and users happy. Decisions about retiring applications consider their business value, cost-effectiveness, security, and performance to align with goals of operational efficiency and modern technology.
Retain
In cloud migration, the term “retain” refers to the strategic decision to keep some systems or applications in their current environment instead of moving them to the cloud. This decision is usually influenced by cost considerations, regulatory compliance, or application complexity. The “retain” strategy recognizes that not all applications will benefit from cloud migration and that some are better suited to stay on-premises.
A crucial choice in cloud migration is whether to migrate or keep apps, which calls for a thorough grasp of the functions of each program inside the company as well as the possible effects of transfer.
Determining whether the complexity and interdependence of the application render migration impossible or excessively costly. Migrating complex legacy systems with many dependencies could be more difficult and expensive. What would happen if its surroundings were changed, and how well is the application connected into the business processes that are in place now?
Some industries have rules that may require certain applications to be kept on-premises instead of in the cloud due to data handling and privacy concerns. It’s important to ask if there are specific regulations that necessitate this. Additionally, for applications that need low latency and high performance, an on-premises setup might work better. Questions to consider include whether the application requires real-time processing or high-performance computing.
Repurchasing
Repurchase is often referred to as “drop end shop. ” Companies may end licensing and switch to new platforms or services. This can involve moving to a different CRM system or sector-specific application. Modern application code allows easy transfer between providers, reducing the need for changes in many cases. Repurchase strategies are common with proprietary products or data-based platforms.
Because of its specificity or the low cost of cloud adaptation, this hybrid approach keeps some of your legacy software on-premise. transfer between cloud servers. Cloud-to-cloud migration, another helpful strategy, is a straightforward provider switch made because some essential features are lacking or there are just better options. Microsoft, Amazon, and Google all have migration tools integrated into their products. Among their features are data migration tools, progress tracking, and the ability to identify possible problems. A portion of them are covered by the subscription, but most will incur additional fees. Selecting an appropriate migration plan is a difficult choice that is impacted by several variables. That being said, it will be just one of many steps you take to get to the cloud.
