What is Lift and Shift Migration
Lift and Shift Migration refers to moving an application, along with its data and configurations, from its current environment (which could be on-premises or a different cloud provider) to a new cloud environment with minimal modifications to the application architecture. In some cases, the move involves lifting the application the way it is and shifting it to a new cloud hosting platform without any changes to the application codebase and database.
Businesses considering application migration consider Lift and Shift migration to a new host as a simple, practical approach that gets the job done with little to no headaches.
The Benefits of Lift and Shift Migration
Here’re some benefits of this simple application migration strategy:
Lift and shift migration enables businesses to transition current apps to the cloud without significant redesign or re-coding. This allows them to bypass most challenges of the migration process and allows them to reap the benefits of the cloud sooner.
Lower Overall Operational Risk
Because lift and shift need minimal changes to the application, the possibility of encountering operational issues and interruptions in end-user services is greatly reduced. This results in a more seamless migration experience with fewer operational problems.
While the migrated application may not initially fully capitalize on cloud-native features, the cost savings from not having to bypass the entire program can be significant. Businesses can optimize and modify the architecture of their applications over time to match with cloud best practices.
Current Skill Set Utilization
Using lift and shift migration, organizations can leverage their existing knowledge and skills in application development and management. As a result, teams can concentrate on moving the application rather than learning entirely new cloud-native technologies.
Simpler Cloud Adaptation
Lift and Shift migration is perhaps the simplest strategy for moving business apps and processes to a cloud environment. Once there, the business may gradually leverage the native cloud services to enhance their application’s capabilities.
Minimum Compliance Issues
Business applications are often subject to rigorous compliance requirements. These regulations lay down application structure constraints that often don’t translate well to the cloud. In these cases, Lift and Shift offers a simple way of complying with regulatory requirements while hosting the applications on the cloud.
Legacy Application Migration
Lift and Shift is a great migration strategy for legacy apps that are difficult to re-architect. Businesses can continue to use these applications in a more scalable and dynamic cloud environment without worrying about the conflicts in the legacy codebase.
Transition to a Hybrid Cloud
Lift and Shift can be used as part of a hybrid cloud strategy, where some workloads are moved to the cloud while others remain on-premises. This method enables businesses to balance cloud adoption with existing infrastructure.
Variations in Lift & Shift Strategies
The great thing about lift and shift migration is how businesses can implement the idea. This introduces a lot of flexibility into migration planning, and businesses can fine-tune critical aspects to fit their requirements.
Here are some implementation ideas that demonstrate this idea’s flexibility and the breadth of the implementation spectrum.
Lift and Shift (Rehosting)
- Methodology: In Lift and Shift migration, applications are migrated to the cloud with few adjustments. The emphasis is on mimicking the current environment with minimum changes to the codebase.
- Goal: The primary goal is to migrate while minimizing disruptions and changes to the application’s architecture.
- Benefits: The process migrates the apps much faster than other options, resulting in significant cost savings and low risks. The business doesn’t need to invest in a modified codebase and hire new talent.
Lift, Tinker, and Shift (Re-platforming)
- Approach: This technique requires minor changes to the application during migration to use cloud-native features without completely rebuilding the application architecture.
- Goal: Optimize specific application components to better work with cloud capabilities while minimizing service disruptions.
- Benefits: The business benefits from the cloud-first features while retaining the familiar application structure and processes.
- Approach: The application is completely redesigned or re-coded to utilize cloud-native services and architecture.
- Goal: Optimize the application for scalability, performance, and cost-efficiency to maximize the benefits of moving to the cloud.
- Benefits: Unlocks the full power of the cloud. However, the extent of the benefits depends upon the business’s investment in time, resources, and knowledge.
- Approach: In this case, businesses replace their existing application with a commercial off-the-shelf (COTS) solution or a SaaS application.
- Goal: Adopt a pre-built solution quickly to add additional features and make the application a better fit for the business objectives.
- Benefits: Faster access to new features and lower maintenance costs. However, this move can result in changes to business procedures.
Retire or Keep

- Goal: Optimize resource consumption and server performance by removing superfluous applications and modules.
- Benefits: It reduced complexity and costs while improving resource allocation.
Adoption of Hybrid Cloud
- Approach: Businesses utilize a mix of on-premises and cloud resources, allowing them to move components to the cloud or keep them on-premises.
- Goal: Increase process flexibility, optimize resource allocation, and save the costs of a full-scale transfer when certain workloads are better suited for on-premises hosting.
- Benefits: Balances the costs of cloud hosting with existing infrastructure investments.
Challenges in Lift and Shift Migration
Like all migration strategies, Lift and Shift has its share of challenges. Businesses should carefully evaluate the idea to see if it is the best fit for their requirements.
In particular, the business should consider the following factors before finalizing any migration plan.
Disruption in Business Operations
Any migration involves disruption in ongoing business operations. Users can’t access applications and business processes as the application goes offline at the current hosting platform during the migration.
The choice of migration strategy should ideally remove or significantly minimize these disruptions so that the users experience a small outage window.
Due to the familiarity bias, businesses try to keep the applications and processes as close to the original state as possible. However, all migration plans require a level of change to the existing applications.
This could become a blocker in the migration process because business users often don’t wish to spare time and effort to relearn skills they were familiar with in the previous environment.
The Challenge of Legacy System
Businesses often see legacy applications and systems as investments. As such, they often don’t wish to lose this investment after the migration.
While Lift and Shift migrations often mean minimal disruptions, there’s always a chance that the legacy applications might no longer be compatible with the new hosting environment. This means significant refactoring or ditching the legacy systems for better and newer systems.
Uncertainty About Cloud Security
During migration, businesses might face temporary security issues. These concerns about data breaches and loss of control are valid when sensitive data and apps are moved to the cloud. The migration plan should address these concerns to help the management make informed business decisions.
The Need to Balance Speed and Quality
The business requirement to relocate quickly might occasionally clash with the desire to migrate in a well-planned, high-quality manner. As businesses struggle to strike a delicate balance between speed and quality, the pressure of deadlines can contribute to feelings of stress and dissatisfaction.
Handling Change Management
Change is an emotional process, and a successful lift and shift migration requires changing the technology and how people operate and interact with it. When transitioning to new cloud-based workflows, employees may face resistance, misunderstanding, or even serious misgivings. Managing the emotional side of change is just as crucial as the technical side.
The Cost Issues
While Lift and Shift is frequently regarded as cost-effective, the financial side of migration can nonetheless create mental distress. Budget limits, unanticipated expenses, and uncertainty about the return on investment contribute to financial anxiety.
The Checklist for a Lift and Shift Migration
Preparing for a Lift and Shift migration is an important step in the migration process. It lays the groundwork for a smooth move of your applications and data to the cloud while minimizing disturbance.
