Navigating ERP Sunsets

Understanding, Migrating, and Mitigating Risks

When ERP systems are being sunset, what does it mean?


In the dynamic world of business technology, Enterprise Resource Planning (ERP) systems play a pivotal role in helping organisations streamline their operations and enhance overall efficiency. However, like all software, ERP systems have a lifecycle, and understanding the implications of reaching the end of that lifecycle is crucial for businesses. In this blog, we’ll explore what ERP systems are, the challenges companies face when these systems reach their sunset, and the strategies employed to migrate data. Additionally, we’ll delve into the risks associated with continuing to operate on sunset ERP systems.

What Are ERP Systems?

ERP systems are integrated software solutions designed to manage and consolidate various business processes and functions within an organisation. These processes often include finance, human resources, supply chain management, customer relationship management, and more. By providing a centralised platform, ERP systems enable efficient data management, collaboration, and informed decision-making, fostering a cohesive organisational structure.

ERP systems typically consist of modules tailored to specific business functions, offering a comprehensive approach to resource and information management.

The Lifecycle of ERP Systems

The lifecycle of ERP systems mirrors the typical stages of software development, from introduction and growth to maturity and eventual decline. When an ERP system becomes outdated or cannot adapt to evolving business needs and technological advancements, it enters the sunset phase.

What Happens When ERP Systems Get Sunset?

Sunsetting an ERP system involves discontinuing support, updates, and maintenance from the software vendor. Organisations relying on a sunset system may encounter several challenges:

  1. Security Vulnerabilities: With no regular updates and security patches, sunset ERP systems become susceptible to cyber threats, putting sensitive data at risk.
  2. Compliance Concerns: Outdated ERP systems may not align with the latest regulatory requirements, exposing organisations to legal and compliance risks.
  3. Reduced Functionality: As technology advances, sunset ERP systems may lack essential features and capabilities, hindering operational efficiency and limiting growth opportunities.
  4. Inefficiency and Productivity Loss: Outdated systems hinder operational efficiency, leading to decreased productivity and competitive disadvantage.

Coping with Migration Challenges

When a company faces the inevitable need to migrate from a sunset ERP system, the process can be intricate. Here are strategies companies commonly employ to cope with migration challenges:

  1. Thorough Assessment and Planning: Organisations conduct a comprehensive analysis of their current ERP system, identify business requirements, and develop a meticulous plan for the migration process.
  2. Data Cleansing and Validation: Ensuring data accuracy and integrity is crucial. Companies invest time in cleaning and validating data to prevent errors and inconsistencies in the new system.
  3. Employee Training: Migrating to a new ERP system often requires employees to adapt to new processes. Comprehensive training programs help ease this transition, ensuring a smoother integration.
  4. Engaging Stakeholders: Involving key stakeholders throughout the migration process is essential. Their insights and feedback contribute to better decision-making and acceptance of the new system.
  5. Incremental Implementation: Some organisations adopt an incremental approach, implementing the new ERP system module by module to minimise disruptions and allow for continuous improvement.OR
  6. Introduce a 3rd Party: Some organisations know that trying to complete the intricate data migration will delay, go way over budget, or fail. They work with companies like us, DataMC, who have a unique toolset to migrate any legacy to any target.


In conclusion, understanding ERP systems, recognising the implications of sunset phases, and effectively navigating migrations are imperative for businesses. The risks associated with operating on sunset ERP systems underline the importance of proactive measures and strategic decision-making. By embracing the challenges and opportunities presented by technological evolution, organisations can ensure their sustained success in an ever-changing business landscape.
