Did you know that Netflix is one of the biggest clients for AWS? They did not just push a button when they shifted their entire data infrastructure. It took them seven years to complete the entire migration and ensure that every piece of data moved securely and perfectly into the new system. This shows us how challenging data migration can be and how crucial it is to have the right team.
Bloor Research surveyed the data migration market and found that 38% of data migration projects fail to meet their goals due to a lack of proper planning and teamwork. If Netflix invested resources to get the perfect team for their huge migration project, it would show just how important proper planning and the right roles are. In this blog, we will explore together what makes a successful data migration team.
What is Data Migration?
Data migration is the process of moving data from one system to another. It is required when organizations upgrade their tech infrastructure, switch to new software, or merge businesses. It is more than just moving data; it requires proper planning of data extraction, transformation, and loading to ensure that data is accurately working and being transferred with security and integrity in the new environment.

Why is a Dedicated Team important?
Data migration is complex and risky. The project can easily lose control, leading to data loss, data breaches, and unhappy clients without the right people and expertise. When you have the right team with defined roles, you have a higher chance of success – the project stays on track, risks are minimized, and business is running smoothly.
For instance, a large retail chain like Walmart plans to migrate customer data to a new CRM system. Due to proper planning and a dedicated team with defined roles and structure, they can complete the data migration with zero customer data loss. They have an IT project manager managing the entire process, a data engineer building the ETL pipelines, data analysts ensuring data integrity, and other roles that support other issues that arose.
Key Roles in Data Migration Team
A successful project depends on a team with defined roles. Roles are not always the same, can be fluid, and responsibilities often overlap.
For a smaller team with limited resources, the data team structure could look like this:
But for larger organizations, here is a breakdown of how the team structure for a data migration project might be:

Skills:
- Technical knowledge in ETL tools and programming languages like Python and SQL
- Knowledge of cloud platforms and big data environments
- Experience in databases and data integration.
- Knowledge and application of data security practices during migration.
5. Data Quality Analyst
The Data Quality Analyst role is to ensure that the data meets the required standards during the migration. They apply testing and validation techniques during the migration processes to compare the input and output data and provide insights of the quality.
Skills:
- Expertise in data quality and validation techniques.
- Strong analytical skills for identifying data issues.
- Experience with data quality tools.
6. Business Analyst
The Business Analyst acts as a bridge between the technical team and non-technical business stakeholders. They translate technical details into business requirements and ensure that everything aligns with business needs.
Skills:
- Strong understanding of business processes and data requirements.
- Good communication with both technical and non-technical stakeholders.
- Experience in requirements gathering and documentation.
- Analytical skills to assess the migration’s impact on business operations.
7. Security Specialist
The Security Specialist ensures data security, implements necessary security protocols, and ensures data compliance. Security essentially revolves around data encryption, access controls, or GDPR guidelines. They work on all security concerns that may arise during the data migration.
Skills:
- Deep knowledge of data security principles and practices.
- Experience with encryption, access controls, and security compliance.
- Familiarity with GDPR guidelines or other data regulation acts.
8. QA Engineers
QA Engineers play a key role in performing software and quality assurance testing on the data and measuring the accuracy and performance. They identify issues and work with the team to resolve them.
Skills:
- Expertise in software testing and quality assurance methodologies.
- Experience with data validation and testing tools.
- Attention to detail and problem-solving skills.
- Ability to work under tight deadlines.
Additional Supporting Roles
We just discussed the core team players in the data migration team; however, depending on the organization’s scope and resources, several supporting roles could also exist.
1. Database Administrator (DBA)
The Database Administrator manages the databases and troubleshoots any database related issues involved in the migration. They ensure that databases are optimized for performance and that data integrity is maintained throughout the process.
2. IT Support
The IT Support handles the permissions, setup and configuration of the hardware and software environment required for the migration and addresses any technical issues that could disrupt the process.
How Collaboration and Communication Drive Success
Do you think Netflix could have achieved their grand data migration plan without strong teamwork and good communication? The short answer is: No.
Cross-functional collaboration is key in any tech-driven and innovative company. When team members work together, the project is more likely to stay on track, meet deadlines, and avoid setbacks. Without it, such large organizations are likely to fail in their goals.
Cross-Functional Collaboration
Data migration projects often involve team members from various departments, such as IT, business operations, security, etc. Supporting cross-functional cooperation ensures that every aspect of the migration is considered, from technical specifications to business needs.
Clear Communication Channels
Tools like Slack, MS Teams, and Jira can facilitate real-time communication and help track progress. This includes regular updates, status reports, and open lines of communication for addressing issues as they arise.
Challenges and Best Practices
Netflix did not close its major data migration project without facing any challenges. They faced the same challenges that every organization is bound to experience in such migration projects, ranging from technical difficulties to organizational resistance. Nevertheless, teams can navigate through the migration process more effectively and increase their chances of success by following best practices.
Data Quality Issues
No one likes poor data quality. It causes disturbances in processes and errors. This can be resolved by applying data analysis and cleaning techniques which the data quality analyst typically conducts. These techniques include identifying and cleaning up duplicates or inaccuracies and implementing data validation checks during migration.
Data Security
We have heard news of many cases of data breaches in companies and public entities. Data is vulnerable to unauthorized breaches and violations during migration, which is extremely concerning when handling sensitive data, like financial or medical information. Implementing strong security measures, such as encryption and protocols, and complying with regulations are major responsibilities of the data security specialist.
User Resistance
Once the migration is completed, we cannot guarantee that all users will adopt the system without any issues. There is usually a lack of change management plans, technical training, and guidance. The migration team should provide support to end-users and assign a change management role to help with transitioning and adoption.
Testing Phase
According to IBM, fixing an error after a product release could be up to 15 times more expensive. This emphasizes the risks of inadequate testing. To fully encompass the migration scope, the team should implement a testing plan that includes unit testing, user acceptability testing, and other applicable test cases. Resolving such issues before the final deployment saves financial resources and time.
Conclusion
Data migration can be challenging, but it is an essential process that requires planning, expert execution, and continuous cross-disciplinary collaboration. We can face challenges in each phase of this migration process, ranging from managing security risks to ensuring data quality and integrity. Nevertheless, with a structured and skilled team, clear communication and adherence to best practices, these challenges can be overcome and success can be achieved.
You cannot achieve a successful data migration by just moving data from one system to another; it needs to be done in a way that aligns with business objectives, minimizes disruption and paves the way for future development. Netflix accomplished this by having a dedicated team with the right blend of skills and a strong collaborative culture.
Data migration is ultimately a strategic activity that can unlock fresh opportunities and ensure that your business stays competitive and adaptable in a rapidly changing world.
