Enterprise System Replacement: A Case Study of Seamless Switchover

The need for enterprise system replacement stems from a variety of factors: for example, the business needs smarter systems to fuel growth, or the business finds a more cost-effective alternative. However, this is no easy task. One of the difficulties is how to minimize downtime while replacing the system.

This article will delve into a real-life case of a top human resources services company to understand how it seamlessly replaced its human resources management system.

Business Structure

In this case, the company’s goal was to replace an outdated human resources management system with a new system. The old system integrated management functions such as employee contracts, payroll, social security, and location. In order to meet the company's new needs, a more feature-rich system needs to be developed. This involves the reconstruction of data stored in the system.

Technical Architecture

The old system is based on Oracle database, and the new system is based on MySQL database. Data exchange takes place via an intermediate Oracle database.

Reasons for adding an intermediate database to your schema include:

• Network Complexity
• Continuous human resources service needs based on production data and data security
• There are differences in how the old system and the new system use the data stored in the database

Challenge

In order to smoothly replace systems while maintaining HR services, live data migration is a critical step. Multiple data pipelines must be built to enable the following data migrations:

• Convert and migrate existing data in the old system to the intermediate database, and synchronize incremental data to the intermediate database in real time.
• Migrate the required data from the new system to the intermediate database, and then load the data from the intermediate database to the old system in real time.

There are the following difficulties in this process:

• Maintain stability across multiple data pipelines.
• Ensure data accuracy across replicated heterogeneous data sources.
• Minimize latency. Keep the delay to a few seconds.
