The 8 Steps for Successfully Migrating Your Legacy Database

Before you begin migrating legacy systems to new platforms, it’s important to understand that there are multiple steps you must follow in order to avoid costly data loss or migration failure.

To ensure your legacy system migration goes smoothly, we’ve prepared a list of the eight most important steps that are critical to successful data migration from legacy systems .

1. Identify all Existing Legacy Data Points

Before a migration, you need to understand which legacy data will be moved. You should examine and categorize each legacy database , identifying and cataloging all data sets stored in your existing systems . 

According to Gartner, an estimated 83% of data migrations fail or exceed their budgets due to poor understanding of the source data.

2. Design Your New Data Model

Ensuring you have a properly designed data model for your new system is crucial. This model should be robust, scalable, and adaptable as your business processes change over time.

It should also ensure that any reads and writes to the database are efficient, minimizing the time consuming task of data conversion during the migration process .

3. Develop a Migration Strategy

A robust migration strategy is critical to ensuring your migration of legacy systems goes smoothly. This strategy should cover any potential risks and include a contingency plan. 

A study from Velostrata and Dimensional Research showed that 73% of businesses said that their data migration process would take from one to two years. 

Of that amount, 30% said their legacy data migration would take between one and two years, while 43% said their data migration process would take more than two years to complete. This further emphasizes the need for careful strategic planning.

4. Ensure Data Quality

To ensure a successful migration, it’s important to maintain data quality during the migration of legacy systems . This includes verifying the integrity, accuracy, and consistency of your data. Poor data quality can cost businesses up to $15 million annually , per a report from Gartner.

5. Implement Migration Solutions

The choice of migration solutions depends on the legacy software you’re using, the database design of the new system, and the data types in question. There are a wide variety of solutions available, including custom-scripted solutions, ETL tools, and middleware.

6. Migrate Your Data

This step involves migrating legacy systems , including all relevant data, from the legacy database to the new system. To that extent, you should make sure the migration process takes place with minimal disruption to your regular business operations .

7. Test the New System

Once the data migration from legacy systems is complete, you should test the new system. This can be done by comparing output data in the new system with the old legacy system to ensure consistency.

8. Ensure Data Security

During and after your legacy systems migration , data security should be a primary focus. You should always have strong security measures in place to protect your data during the transition and after it’s transferred to the new system. 

IBM’s Cost of a Data Breach report found that the average cost of a data breach in 2022 was $4.35 million , emphasizing the need for effective data security.
