aws migration best practices

Cloud migrations have become crucial to many business operations. Whether you’re a small business, a tech startup, or an enterprise company, shifting to the Amazon Web Services (AWS) cloud can offer many benefits. However, this process can be daunting without proper guidance. That’s where Oak Rocket comes in.

In this post, we’ll walk you through the AWS migration best practices, highlighting Oak Rocket’s unique services that can help make your migration successful.

AWS Migration Best Practices

Migrating to AWS is a significant step for any organization. It requires careful planning to ensure a seamless transition and avoid potential pitfalls. Here’s how you can effectively plan your AWS migration:

Define your objectives

Before starting the migration, it’s crucial to define your goals clearly. Why are you moving to AWS? Is it to scale your infrastructure, improve security, cut costs, or increase agility? Having clear objectives will guide your decision-making throughout the migration.

Assess your current environment

Take stock of your existing IT landscape. This includes understanding your applications, data, and infrastructure. Identify which applications are critical for business operations, which can be retired, and which need to be re-architected for the cloud.

Choose the right migration strategy

You can choose from several migration strategies – rehosting (lift-and-shift), replatforming, refactoring, etc. The right strategy depends on your business needs, technical requirements, and budget.

Estimate costs

Moving to the cloud can save you money in the long run but it also requires an initial investment. Make sure to estimate the cost of migration, including the cost of any necessary tools, services, and resources.

Develop a timeline

Create a realistic timeline for your migration. This should include time for pre-migration tasks, the actual migration, and post-migration optimization.

Plan for security and compliance

Security is a top priority in any migration. Plan how you will maintain security during the migration and comply with relevant industry regulations.

Oak Rocket’s migration planning service can help you in all these steps. With our deep expertise in AWS and migration planning, we can help you create a comprehensive migration plan tailored to your needs while adhering to AWS migration best practices.

By following these steps, you can ensure that your migration to AWS is well-planned and set up for success. Remember, a good plan is the foundation of a successful migration.

Pre-Migration Tasks

Once you have a plan, start preparing your data for the move. This involves cleaning up your existing system, backing up data, and setting up security measures. Utilize Oak Rocket’s Pre-Migration services for seamless and efficient preparation.

Here’s a detailed breakdown of the Pre-Migration tasks to consider:

  1. System Cleanup: Review your current system and identify any outdated or unnecessary data that can be cleaned up before the migration. This might include old log files, unused applications, and redundant data.
  2. Data Backup: Having a recent backup of all your data is crucial before beginning the migration process. This provides a safety net in case something goes wrong during the migration.
  3. Security Measures: Implement necessary security measures to protect your data during the migration. This could include encrypting sensitive data, setting up firewalls, and ensuring secure connections for the data transfer.
  4. Resource Allocation: Determine the resources needed for the migration process. This includes technical resources like bandwidth, storage, and human resources; you’ll need a dedicated team to manage the migration.
  5. Downtime Planning: Some downtime is often necessary during a migration. Plan this carefully to minimize disruptions to your business operations. Consider scheduling intensive migration tasks for off-peak hours.
  6. Testing Environment Setup: Set up a testing environment where you can trial the migration process and solve any issues before they impact your live system.
  7. Migration Tools Selection: Identify the tools and technologies you’ll use to facilitate the migration. AWS offers a range of tools like the AWS Migration Hub, AWS DMS (Database Migration Service), and AWS S3 Transfer Acceleration.
  8. Detailed Migration Plan: Create a detailed migration plan based on all the above factors. This should include the order in which data and applications will be migrated, the expected timeline, and contingency plans for potential issues.

Please remember that thorough preparation is critical to a successful migration. By planning and preparing carefully, you can ensure a smooth transition to AWS with AWS migration best practices.

The Migration Process

This is where the actual move takes place. Choose an appropriate migration strategy – rehosting (lift-and-shift), replatforming, refactoring, etc. Oak Rocket’s Migration Execution Service, equipped with advanced tools and experienced personnel, ensures a smooth transition to AWS.

Example Migration Process:


You’ll start the migration process at this stage by communicating the plan to all stakeholders, assembling your migration team, and setting up the necessary tools and resources.

Data Migration

Begin migrating your data to AWS using your selected tools and strategies. This could involve moving data in batches or using a continuous replication strategy to minimize downtime.

Application Migration

After your data is securely hosted on AWS, you can start migrating your applications. Depending on your chosen strategy, this might involve rehosting (lift-and-shift), replatforming, or refactoring your applications for the cloud.


Once your data and applications are in place, you’ll need to conduct thorough testing to ensure everything works as expected. This should include performance testing, security testing, and user acceptance testing.

Switching Over

When you’re confident your new AWS environment is ready, it’s time to switch over from your old system. This should be carefully planned to minimize disruption.


After the migration, continuously monitor your new environment to ensure everything runs smoothly. AWS provides various tools for monitoring performance, usage, and costs.


The final step in the migration process is optimization. Review your new setup and look for opportunities to improve efficiency, reduce costs, or enhance performance. This might involve fine-tuning your configuration, scaling resources up or down based on demand, or taking advantage of additional AWS services.

Remember, migrating to AWS is a significant undertaking, but with careful planning and execution, you can minimize disruptions and maximize the benefits of the cloud.

Post-Migration Activities

After the migration, it’s essential to validate the performance and functionality of your applications. Oak Rocket’s Post-Migration Optimization service helps fine-tune your AWS environment while optimizing your new environment to ensure cost efficiency and performance.

Sure, here’s a detailed breakdown of “Post-Migration activities” based on the outline provided:

  1. Performance Monitoring: After the migration, closely monitor system performance to ensure it meets or exceeds the baseline established pre-migration. Use monitoring tools offered by AWS, like CloudWatch and X-Ray.
  2. Security Auditing: Conduct a thorough security audit post-migration. Check that all data is secure, access controls are correctly implemented, and there are no vulnerabilities.
  3. Cost Monitoring and Optimization: Monitor your AWS usage and costs to ensure they align with your estimates. AWS Cost Explorer can provide insights here. If costs are higher than expected, look for ways to optimize, such as using reserved instances or turning off unused resources.
  4. System Optimization: Post-migration is the time to fine-tune your system. Look for ways to improve efficiency, reliability, and performance. This could involve leveraging more AWS services, adjusting resource allocation, or refactoring applications for better cloud compatibility.
  5. Staff Training: Ensure all users are comfortable with the new system. Provide training as necessary on how to use and manage the AWS environment.
  6. Documentation Update: Update your system documentation to reflect the new AWS environment. Include details about the infrastructure, applications, processes, and any changes made during the migration.
  7. Continuity Planning: Establish a disaster recovery plan in case of a failure. AWS provides services like S3 for backup storage and Glacier for long-term archiving.
  8. Regular Review: Schedule regular reviews of your AWS environment. These reviews can help you keep up with changes in your business needs, AWS services, and industry best practices.

Remember, the work continues once the migration is complete. Continuous monitoring, optimization, and regular reviews are vital to getting the most out of your AWS environment and completing AWS cloud migration best practices.
