Cloud Migration Strategies: Transform Your Legacy Systems to Cloud Infrastructure

Cloud migration is the process of moving an organization’s data, applications, and infrastructure from on-premises to cloud-based infrastructure. The cloud has revolutionized the way businesses operate by offering scalable and cost-effective infrastructure that can be accessed from anywhere.

In this article, we will explore cloud migration strategies and learn why they are necessary for businesses looking to transform or upgrade their legacy systems to digital infrastructure. Besides, we will also discuss the advantages of cloud computing, market trends, and why Odyssey Analytics is the best partner for cloud migration.

Why Your Business Needs Cloud Migration

Cloud migration offers multiple benefits to organizations, including scalability, cost savings, accessibility, and security. Moving to the cloud can result in significant cost savings as organizations no longer need to invest in physical infrastructure, hardware, and maintenance.

Cloud computing provides on-demand scalability, allowing organizations to quickly and easily tune their infrastructure resources based on business needs. The cloud can be accessed from anywhere, making it convenient for corporations to access their infrastructure and data remotely. On the other hand, there are different strategies that companies opt to embrace for digital transformation.

Types of Cloud Migration Strategies

There are several cloud migration strategies that organizations choose according to their business goals, scalability, and AI advancements. These strategies include:

  • Rehosting (also called Lift and Shift)

    Rehosting is all about moving existing applications and data to the cloud without making any significant changes. Lift & Shift strategy is best suited for organizations that want to move to the cloud quickly without making any major changes to their existing infrastructure.

  • Replatforming (also called Lift, Tinker, and Shift)

    This strategy involves moving applications to the cloud while making some minor changes to the underlying infrastructure. This strategy is best suited for organizations that want to optimize their applications for the cloud without investing in significant changes.

  • Refactoring (also called Re-architecting)

    This strategy involves making significant changes to an organization’s applications and infrastructure to optimize them for the cloud. This strategy is best suited for organizations that want to take full advantage of cloud-based infrastructure and services.

  • Repurchasing (also called Replacing)

    An famous data migration strategy where a legacy system is replaced with a cloud-based software as a service (SaaS) platform. This strategy involves reimagining the whole organization’s infrastructure to a remote but fully managed third-party platform.

  • Retaining (also called Revisit)

    A unique cloud migration strategy where applications or legacy systems do not make sense in cloud transformation. The system might lack some system information or perform well on the legacy systems than the conventional system.

  • Retiring (also called Retain)

    Retiring in cloud migration is all about minimizing system workloads by eliminating useless or retired services. The applications or sub-services whose availability does not make any sense over the cloud.

Every cloud migration strategy discussed above has its own advantages and disadvantages. The 6 R’s in cloud migration leverage businesses to choose the best possible cloud transformation for their legacy systems. Energy strategy has its own advantages for high-level executives and software development teams.

Advantages of Cloud Migration to Companies & Stakeholders

The advantages of cloud migration are numerous and include:


The cloud offers on-demand scalability, allowing organizations to easily and quickly increase or decrease their infrastructure resources based on business needs.

Cost Savings

Moving to the cloud can result in significant cost savings as organizations no longer need to invest in physical infrastructure, hardware, and maintenance. Cloud computing providers such as AWS, GCP, Microsoft Azure, and IBM cloud offer pay-as-you-go facilities. It means that you will pay only for resources that your company consumes.


The cloud can be accessed from anywhere, making it convenient for organizations to access their infrastructure and data remotely. In addition, it has pre-deployed open-source APIs and third-party integrations to easily scale the infrastructure.

Better Integrations

Allow systems to interact with each other more efficiently and enhance system capabilities with add-ons.


The cloud offers robust security features that can protect data and applications from threats such as malware, session hijacking, SQL injection attacks, and data breaches.

The Benefits of Cloud Computing

In addition to the advantages of cloud migration, cloud computing offers numerous benefits to organizations that result in business success. It has a bunch of benefits starting from the operations to the finance department.

  • Flexibility

    Cloud computing allows companies to access infrastructure and services on demand, allowing them to quickly adapt to changing business needs. Instead of wholly managing on-premises storage and computing powers cloud-based systems are providing flexibility to businesses around the sphere.

  • Innovation

    Cloud computing provides access to cutting-edge technologies that can help companies innovate and stay ahead of the competition. These computing services leverage research and development teams to utilize pre-deployed machine learning and deep learning models with the option to drag & drop into production in a few clicks. Therefore, it results in quick data analytics and business intelligence.

  • Collaboration

    Cloud computing makes it easy for teams to collaborate on projects and share information from anywhere in the world. In addition, cloud computing also results in business partnerships and collaborations where data ingestion has become cheaper than before.

How Does the Cloud Migration Process Work?

The cloud migration process is a multi-stage process so that’s why we divided it into different steps as below:


The first step is to assess an organization’s existing infrastructure and applications to determine the best cloud migration strategy.


Once the assessment is complete, the next step is to develop a detailed plan for the migration, including timelines, budgets, and resources.


The migration process begins with moving applications and data to the cloud based on the chosen migration strategy.


Once the migration is complete, the final step is to optimize the underlying cloud infrastructure and applications for maximum performance and efficiency.
