Data migration without errors - How to do it?

2023.10.18.
In our data-centric world, in order to operate smoothly and make decisions, businesses greatly need error-free data migration. However, data migration is a very complex process that is often a challenge for companies. In our article, we present the best practices and strategies for error-free data migration.

What is data migration?

For companies dealing with huge amounts of data, data migration is the transfer of some or all of the digital data from one software or hardware to another software or hardware. By migrating data, data stored on outdated IT systems and softwares are transferred to IT systems and softwares with higher capacity that better meet current needs. The goal of data migration is to guarantee the security of critical data to the company.

Data migration is therefore the process of transferring data from one system or platform to another. Data migration is crucial for businesses looking to upgrade their systems, consolidate databases, or move to cloud-based solutions. Successful data migration ensures data integrity, accessibility and reliability.

Error-free data migration

How can we ensure that our existing data is transferred from old software to new software without errors? Below, we list the six essential points that are essential for the migration of our data to take place with the fewest errors.

1. Planning and preparation

The start of the data migration project is preceded by thorough planning and preparation. This includes defining the scope of the migration, mapping the data flow and setting clear goals. A well-prepared migration plan helps to minimize errors and ensures a smooth transition of data.

2. Data cleaning and validation

Data cleansing is a critical step to ensure the accuracy and quality of migrated data. This includes identifying and correcting inconsistencies, duplications and inaccuracies in existing data. During data migration, it is necessary to use data validation techniques to check the integrity and reliability of the migrated data.

3. Creation of data migration protocols

In order to avoid errors during data migration, it is essential to create standardized protocols. These protocols should include data extraction, transformation and loading (ETL) policies. By following a defined set of protocols, organizations can minimize the risk of data breach and ensure consistency.

4. Testing and inspection

Performing full testing and verification is essential to identify and correct any errors or discrepancies in migrated data. This includes performing sample tests, comparing data between source and target systems, and validating data against predefined rules. Regular testing during the transition process helps to detect and correct errors before they negatively affect the day-to-day operations of the company.

5. Data backup and contingency planning

Data migration comes with risks, so it is crucial that your organization has backup and contingency plans in place. Regular data backup ensures quick recovery from unforeseen errors or data loss. In addition, contingency plans help mitigate risks and minimize potential disruptions during the relocation process.

6. Follow-up and post-migration analysis

Even after a successful data migration, continuous monitoring of the migrated system is essential to ensure the accuracy and integrity of the data. Monitoring tools can help identify any abnormalities or errors that may occur after migration. In addition, post-migration analysis allows organizations to evaluate the success of the migration and make necessary adjustments.

Requirements of a data-centric environment

Error-free data migration is key to sustaining the long-term success and growth of businesses. By systematically implementing the activities outlined in the seven points above, organizations can minimize errors, ensure data integrity, and achieve a smooth transition. So it cannot be emphasized enough: careful planning, thorough testing and continuous monitoring are key to achieving error-free data migration.
