A top HR service company seamlessly replaces its system with BladePipe

Enterprises often face huge challenges in replacing systems, such as upgrading human resource management systems (HRMS), especially in minimizing downtime. This article will use a real-life example to illustrate how a top HR service company can seamlessly replace its HRMS system with data migration tools.

Business architecture and requirements

The company aims to replace the old system with a more powerful new HRMS system. The old system covers information management such as employee contracts, salary, social security and office locations. The new system needs to process more data, so the data storage in the system needs to be rebuilt.

Technical architecture and data migration strategy

The old system is based on Oracle database, while the new system uses MySQL database. To ensure the continuity of HR services during system replacement and to address network complexity and data security needs, the company cleverly designed an intermediate Oracle database as a data exchange hub. This solves the problem of the difference in database structure between the old and new systems.

Challenges and solutions

In order to achieve a smooth system transition, real-time data migration is crucial. This requires building multiple data pipelines to complete the following tasks:

• Convert and migrate legacy system data to an intermediate database and synchronize incremental data in real time.
• Migrate the necessary data from the intermediate database to the new system and load the data to the old system in real time.

This process faces the following challenges:

• Maintain the stability of multiple data pipelines.
• Ensure the accuracy of data migration between heterogeneous databases.
• Control the delay to within seconds.

Why choose BladePipe?

After comparing multiple data migration tools, the company finally chose BladePipe for the following main reasons:

• Intuitive interface to configure data pipelines without code.
• Automatically complete architecture migration, full data migration and incremental data synchronization.
