AWS Cloud Migration Checklist
Your app migration readiness would define items & priorities on the checklist. Based on our experience, moving smaller applications to AWS Cloud would usually take 1-2 months. Whereas it could take ~6 months and longer to migrate the first medium or large application. It would include factors like the number of workloads moved daily, the chosen approach, applicable compliance regulations, and the complexity of security.
Moving your existing business apps to the AWS Cloud works across stages,
Before the Migration
During this stage, it is imperative to evaluate financial readiness, detailed scope & execution schedule. For this, you need to define the following:
Auditing IT infrastructure & assigning roles
- Short- & long-term goals to be achieved from the migration
- Resources for migrating data and apps
- Teams responsible for every resource
- The size of data centers, databases & apps
- Timelines for each stage
- Data backup tools
- App dependencies & integrations
Creating migrations teams
- Core team – to synchronize resources, build automation solutions, assess risks, and optimize backlogs
- Migration team – to execute the move, automate low-complexity workflows and transfer apps
Assessing financial & technical readiness
- Detailed analysis of the cost for migrating server, network, storage, and other relevant components in the targeted environment.
- App’s architectures & data to be transferred first.
- Possible security risks
- Critical assets to be kept off the cloud
Finding the right technology partner
- Relevant AWS migration case studies of successful transitions
- A proven framework to mitigate risk, reduce cost & ensure data security
- Agile methodology is driven by an industry-leading AWS tech stack
- An experienced and proficient team to assist in hassle-free migration
During the Migration
Here you would review the tools & methodologies required to speed up and simplify the migration,

AWS cloud migration steps
Forklift migration
- A popular strategy that deals with considering all the apps in one go and moving them to the cloud.
- Highly recommended for tightly coupled apps that are stateless and self-contained.
- This approach not only accelerates your infrastructure handling time but also helps optimize resource allocation.
Hybrid migration
- Allows businesses to integrate Office 365 with their existing directory services and on-premises exchange servers for efficient management of user accounts across environments.
- Best suited for businesses with several apps where some are kept intact, and others are moved to the cloud.
- This low-risk approach is time-consuming but if offers optimal results.
Review app migration options
Some widely popular & preferred app migration options are listed below;
- Live migration – moving a running app from its existing physical setup to the cloud platform, without any disruption
- App containerization – adopting an OS-level virtualization approach to deploy distributed business apps
- Data migration – synchronizing business data stored in the machines with the cloud by taking the file format and storage type into consideration
- VM conversion – converting virtual machine disk into a relevant format and transforming the business data using APIs
After the Migration
The task is not yet complete, post the migration exercise, here are few essential considerations;
Leveraging the full potential of cloud
If you want to reap the full benefits of moving to AWS cloud platform, it’s essential to understand AWS enterprise support and services like Amazon Elastic MapReduce, Amazon CloudFront, and auto-scaling.
Tracking & Optimizing
Some cloud monitoring tools that you can use for a hassle-free experience include AWS CloudWatch Logs, APPDYNAMICS, and New Relic. Examine, analyze, and track for more insights on load patterns for efficient management of the cloud environment.
Testing
Perform user acceptance testing to evaluate if the migration was successful. To avoid failure and save time and resources, you can consider working with an experienced AWS consulting partner who is well-versed with the best tools and techniques.

AWS Migration Cost
If you find that cloud migration is costing you higher than your on-premise data center, it’s because you’re comparing a single on-premise server with an AWS compute resource. Don’t make this mistake!
- Comparing the memory sizing or processor of AWS with an on-premise server is like comparing an apple to an orange.
- On-premise pricing is inclusive of workforce, electricity, labor, taxes, data center premises, heating, or cooling. But with AWS, all these expenses are already factored into the TCO.
So, when you consider the total cost, you’d be surprised to know how competitively priced AWS cloud is!
