You can follow this tried-and-tested lift and shift migration process for a swift, seamless, and efficient transition to the cloud. It will also help you maintain your apps’ and data’s integrity and functionality. Check out the essential steps involved in successful cloud migration to make the most out of your cloud journey.
Evaluate the cloud platform that aligns with your business needs and goals. Conduct an assessment of cloud platforms and consider scalability, cost, and compatibility factors. Refer to our comprehensive comparison between AWS and Azure to determine which makes the most sense for your business.
Identify the apps and related data you want to migrate to the cloud. List out all their dependencies and resource requirements that will be needed.
Allocate the necessary tools, budget, and team resources for a swift and seamless migration.
If you plan to lift and shift multiple applications, it is best to independently plan, document and implement each migration. You can also engage an external service provider if you wish to automate the migration roadmap for faster time to market.
Containerization makes it easy for you to capture software systems and their dependencies. It allows hassle-free replication and testing in the cloud environment. This step is also necessary to ensure the software functions as expected before you go live.
Before you start the lift and shift migration, protecting the data in your existing systems is essential. You need to back up the app code, binaries, databases, and file data. Clearly defining your roll-back strategies and thoroughly testing the restore process will make managing failures easy and avoid downtime.
The next step involves creating a cloud account, VPCs, VMs, role-based access controls, and security policies. Do follow the best practices suggested by your cloud provider and industry experts. You may also engage an experienced cloud migration partner for external assistance.
Test your migration carefully during the pre-planned maintenance window and after the application and data have been transferred. These standard validation checks on the recently shifted application will help you quickly identify and address any underlying compatibility or performance issues.
Monitor the underlying infrastructure and resource consumption once the app is up and running. Monitor the app for functionality, efficiency, and resource consumption. This helps ensure strict adherence to regulatory requirements, which will help you avoid legal and compliance issues after moving your apps and data to a cloud platform.
Don’t modify or add new application features while the migration process is still on. Stay focused on maintaining the existing functionality of your apps to minimize the chances of complications or extra testing efforts.
Testing helps verify your apps and services’ performance, functionality, and optimal resource consumption. You can use cloud dashboards for reviewing log files and infrastructure resources and make informed decisions regarding necessary optimizations.
Once the migrated apps are running as expected in the new cloud environment, you can gradually retire your old systems. Doing this will ensure a smooth transition with uninterrupted business continuity.

Compared to running your apps on-premises, adopting the lift and shift cloud migration approach offers the following compelling benefits:
The lift and shift cloud strategy lets you migrate quickly and easily without allocating a dedicated team. Your on-premises apps can continue to run while the migration is in progress, so there’s no downtime, and the end-user experience also remains unaffected.
Lift and shift cloud migration allows your business to run apps on updated, high-performing hardware without needing you to invest in the hardware yourself.
You can add network bandwidth, compute capacity, and storage on a flexible pay-as-you-go plan while simultaneously consolidating your on-premises setup and data center costs.
Opting for the lift and shift migration approach allows you to scale your apps without buying and installing new computing resources. You also don’t end up overprovisioning hardware to handle traffic spikes.
Apps running in the cloud can automatically spin resources up and down to keep up with the sudden peaks and dips in demand. So, you can save significantly by leveraging this agility of the cloud, as your apps will use just the right number of resources as and when needed.
Once moved to the cloud, even legacy apps can leverage the security features of cloud platforms like multifactor authentication, role-based access control, and centralized hybrid security processes.
The more apps and data you move to the cloud, the faster you can downsize your on-premises setup and, with it, the costs, and hassles of managing and maintaining it!
