What Is Migration Testing: How to Efficiently Conduct Testing While Migrating Data?

Migration testing

Technology is ever-evolving with new advancements making its presence every day. Organizations are constantly updating their legacy systems to the new ones to take advantage of these developments and align with the constantly changing end-user preferences. However, the major challenge lies in migrating to the new system without losing data. Data owned by organizations is an asset that provides critical insights to plan future endeavors, hence, organizations cannot afford to lose them.

Though data migration is a tedious process that requires enormous effort and time, it is a significant process that plays a crucial role in application redesign. Data migration cannot yield favorable results without a thorough testing process in place. Migration testing ensures that data integrity is maintained while upgrading, integrating, or transferring the system, while making data migration a success that affects your business positively.

Migration testing ensures the data migration has not resulted in any disruption and all functional and non-functional aspects of applications are retained even after migration. It is extremely important to undertake Data Migration Testing to find out the discrepancies that arise while migrating the data from the parent or legacy database to the new or destination database. Organizations must efficiently conduct testing while migrating data for smooth operations.

The need for migration testing

Testing of the system is critical even when the slightest change is made, to ensure the incorporated change doesn’t create any conflict in the current workflow or make any further unnecessary modifications. Hence, it becomes important to carry out end-to-end testing during the system migration process. Migration testing is essential as it:

  • Ensures continuity and consistency after the platform migration – imagine if your mortgage computation changed because the lender changed systems?
  • Ensures no data loss when you move to the new platform – imagine if your broker could no longer locate your retirement account after her company upgraded their systems?
  • It identifies any defects in the new application and ensures that it works perfectly without any issue.
  • When migrating from one system to another, migration testing ensures proper flow and working of the application, as it was before migration.
  • In addition to testing data retention and functionality checks, migration testing also checks if the application is optimized to the new workflows and environment.

Data Migration Testing Approach

Organizations should incorporate the following strategic approach for data migration testing for best results:

  • Form a specialized team for data migration testing: It is of paramount importance to have a team that possesses the required skill set and experience to carry out data migration testing.
  • Risk and Error Analysis: It is essential to ensure that data migration testing should be smooth and does not disrupt the current business. Data migration testing should focus on high-risk scenarios to validate and mitigate risks.
  • Scope of Migration Testing: Organizations should decide the scope of data migration testing- what is to be tested.
  • Select the Data Migration Testing Tool: An appropriate Data migration Testing Tool should be selected to achieve minimum discrepancies and anomalies.
  • Identify the Test Environment: The test environment should be set up according to the technical aspects of the source and target data system.
  • Migration Test Document: In the end, it is important to prepare a migration test document that states the testing tool, testing methods, schedule of testing, etc.

Data migration testing has assumed a lot of significance in the current scenario, where the availability of the right data at the right time governs the success of any organization. Organizations are investing a huge amount of resources in migration testing to avoid any mishaps later on. Efficient and effective data migration testing combines a systematic approach, prescient risk minimization techniques, and holistic test coverage.

Understanding data migration testing

Efficient data migration testing includes the following two levels of validation testing:

  • Data Level Validation Testing
  • Application-Level Validation Testing

Data Level Validation Testing

When data is moved from several databases to one common database, data level validation testing is done to ensure that there are no discrepancies. It ensures that the complete data is migrated to the new system and no loss was incurred during the migration process. Data Level Validation Testing can be further classified as follows:

Level 1: Counting the number of rows

In his stage, we find out the total number of records that would be moved or migrated.

Level 2: Verification of data

A sample is selected from the migrated data and checked thoroughly to verify the accuracy of the data.

Level 3: Verification of Entitlement

At this stage, the new database is verified for the users as well as samples of data.

Application-Level Validation Testing

Application-Level Validation Testing checks whether the migrated applications function efficiently in the new database or not; a sample application, that was migrated, is tested for its functionality. Following validations are carried out:

  • Verification of sample data by logging into the new application after migration
  • Verification of the status of accounts- whether it is locked or unlocked by logging into the legacy system post-migration
  • Verification of access to legacy systems during migration despite user blockage
  • Verification of instant restoration of user access to the old system in case of failure of migration
  • Verification of denial of access to legacy systems at the time of migration
  • Validation of login credentials for migrated applications

Data Migration Testing Tools

Data Migration Testing Tools can be classified into three categories as follows:

  • On-premise Tools
  • Open-Source Tools
  • Cloud-based Tools

On-premise Tools: When organizations want to transfer data from one server to another or from one database to another within the enterprise, they use on-premise data migration testing tools. In this scenario, it just involves changing the database or integrating databases.

Open-Source Tools: Open-source data migration tools are easily accessible by people. They are free to use. Organizations can use these data migration testing tools if the project is small and the data to be tested is less. Knowledge of coding skills is required if you use open-source tools.

Cloud-based Tools: Cloud-based data migration tools are the latest developments in data migration and testing. These tools enable the organizations to transfer the data to Cloud, which is the need of the hour. Hence, Cloud-based data migration tools are widely used as they are secure, flexible, and cost-effective.
