Data migration is an inevitable process that most businesses will face at some point. It involves transferring existing data from one storage system or computer to another, which can be a complex and daunting task.
However, with the right strategies, you can navigate this process successfully. In this article, we will outline the most effective approaches to help you achieve a seamless data migration.
You will learn what a data migration strategy entails, what to include in it, and what to consider when planning migration. We will also highlight common issues that arise during and after migration, enabling you to avoid unexpected surprises.
Additionally, you will discover how to conduct thorough tests after the migration. Businesses undertake data migration for various reasons, such as replacing servers, transitioning their on-premise IT infrastructure to a cloud computing environment, updating their current database with new data due to a merger or acquisition, or moving their data to a new CRM.
According to statistics, between 70-90% of data migration projects fail to meet expectations. Therefore, it's crucial to follow data migration best practices to ensure a successful process.

Key Strategies for a Successful Data Migration
To help you achieve a successful data transfer, we have outlined 10 data migration best practices below.
Ensure Data Backup and Recovery
In the event of unforeseen circumstances, having a data backup ensures you can avoid potential data loss. If problems arise, such as file corruption, loss, or incompleteness, you can restore your data to its original state.
Assess Data Complexity and Quality
Another crucial best practice for data migration is verifying data complexity to determine the best approach. Assess different forms of organizational data, identify what data to migrate, its current location, storage, and format after transfer.
Evaluate the cleanliness of your current data and determine if it requires updates. Conducting a data quality assessment helps detect the quality of legacy data, implement firewalls to separate good data from bad data, and eliminate duplicates.
Establish Data Standards
Once you understand the complexity of your data, establish standards to identify potential problem areas and avoid unexpected issues at the project's final stage. As data is constantly evolving, setting standards in place ensures successful data consolidation and future use.
Define Current and Future Business Regulations
To ensure regulatory compliance, it is essential to establish current and future business regulations for your data migration process. These regulations must align with various validation and business rules to facilitate consistent data transfer, achievable only through the development of data migration policies.
To ensure a seamless data transition, it's essential to establish a set of guidelines prior to migration and then refine them to increase their sophistication for your data after the migration process is complete.
Formulate a Data Migration Blueprint
A well-planned strategy is crucial to successful data migration. You can adopt one of two approaches: a comprehensive "big bang" migration or a gradual "trickle" migration.
If you opt for the big bang approach, the entire data transfer is completed within a specific timeframe, for instance, within 24 hours. Live systems are temporarily suspended while data undergoes ETL processing and is transferred to a new database. Although quicker, this approach is riskier.
The trickle approach, on the other hand, breaks down data migration into stages. Both systems – the new one and the old one – operate concurrently, eliminating downtime. While this approach is more complex, it is safer, as data is migrated continuously.
Clearly Communicate Your Data Migration Process
The data migration process will likely involve multiple teams. Ensuring you clearly communicate the process to them is a vital data migration best practice. They need to know what is expected of them, which means you need to assign tasks and responsibilities. List all the tasks and deliverables and assign roles to activities. Verify if you have the necessary resources to complete each task.
You must consider:
- who holds the ultimate authority over the data migration process
- who has the power to decide whether it was successfully completed
- who is responsible for data validation after the migration
If you fail to implement a clear division of tasks and responsibilities, it may lead to organizational chaos, delay your migration process, or even result in failure.
Leverage the Right Tools
Envisioning manual script and data migration? Not the most ideal approach. Utilizing the right tools during data migration can significantly expedite and streamline the process. These tools can be utilized for data profiling, discovery, data quality verification, and testing purposes.
Selecting the right migration tools should be a crucial aspect of your planning process. Your choice should be guided by the organization’s specific use case and business requirements.
Develop a Risk Mitigation Strategy
Risk management is a critical consideration during the data migration process. Various challenges may arise, and identifying them while devising strategies to mitigate or prevent them will contribute to a more successful outcome. Consider factors such as deprecated data values, security concerns, user testing, and application dependencies.
Embrace Agility in Data Migration
By adopting an agile methodology during data migration, you can ensure high data quality through iterative testing, detect and rectify errors in real-time, and maintain a transparent process. This approach also facilitates more accurate cost and schedule forecasting, as it requires a clear allocation of tasks and responsibilities and adherence to deadlines.
Key Considerations for Testing
Deferring testing until the data transfer is complete can result in significant expenses. Instead, integrate testing into each phase of the data migration process: planning, design, implementation, and maintenance. This enables you to achieve your desired outcome within the allotted timeframe.
Final Thoughts
Data migration can be a intricate process, but it's an unavoidable step for your organization. To mitigate data loss, ensure you have a backup strategy in place, as unforeseen circumstances can arise. Developing a risk management strategy is vital – identify potential pitfalls and devise solutions to rapidly resolve them.
