ERP Data Migration Guide: Best Practice & Migration Checklist

ERP data migration is one of the most important parts of any successful ERP implementation. Moving data from legacy systems to a new ERP solution is crucial for business continuity, and requires careful planning, precise execution, and thorough validation. If not planned out carefully, you can cause yourself a whole host of issues. 

What is ERP Data Migration?

ERP data migration is the process of transferring data from existing legacy systems to a new Enterprise Resource Planning platform. This data can be anything from invoices, purchase orders, employee data and/or customer data. It's everything that ensures the business can function as normal. The process involves extracting data from source systems, transforming it to meet the requirements of the target ERP system, and loading it into the new environment.

The accuracy and integrity of migrated data directly influences the effectiveness of your new ERP system. Incomplete or inaccurate data migration can result in operational disruptions, flawed reporting, and compromised decision-making capabilities.

Why ERP Data Migration Matters

Effective data migration forms the foundation for ERP implementation success. According to a 2023 Gartner study, approximately 40% of ERP implementations exceed their budgets due to data migration complications, and nearly 30% fail to deliver expected benefits because of data quality issues.

When executed properly, data migration:

• Ensures business operations continue smoothly during the transition
• Provides accurate historical information for analysis and reporting
• Maintains data consistency across organizational functions
• Reduces the risk of operational disruptions post-implementation

Common Challenges in ERP Data Migration

Organizations frequently encounter obstacles during the migration process. Some of these include:

• Data quality issues: Duplicate records, outdated information, and inconsistent formatting complicate the migration process and compromise data integrity.
• Complex data mapping: Matching fields between legacy and new systems often reveals incompatibilities in data structures, requiring careful planning and technical expertise.
• Business disruption concerns: Migration processes can potentially interrupt normal operations, necessitating detailed planning to minimize downtime.
• Integration complexity: Ensuring the migrated data works properly with connected systems and applications requires comprehensive testing and validation.
• Resource constraints: Limited technical expertise and competing priorities can hinder migration efforts if not properly addressed.

ERP Data Migration Best Practices

Start with a Clear Migration Plan

Develop a detailed migration strategy with defined scope, timeline, and objectives. Your plan should identify:

• Specific data sources to be migrated
• Priority order for data migration
• Key milestones and deadlines
• Success criteria for the migration

Assemble a Dedicated Migration Team

Form a team comprising members from IT, business departments, and ERP specialists. Ensure representation from all departments affected by the migration to address various data requirements and use cases.

Conduct Thorough Data Auditing and Cleansing

Before migration begins:

• Identify and remove duplicate entries
• Correct inaccurate information
• Standardize data formats
• Archive obsolete data that doesn't need migration

Research shows that organizations that invest in data cleansing before migration experience 30% fewer issues during implementation.

Top Tip: Migrating data is a time consuming and costly process. Try and migrate as little data as you can. We normally advise migrating 1 years worth of data, as this gives you enough to have an accurate overall picture of the business, but not enough that your migration costs are going to be too high. 

Select Appropriate Migration Tools

Select migration tools that are fully compatible with both your existing legacy systems and the new ERP platform to ensure a seamless transition. This involves evaluating the technical specifications and capabilities of potential tools to confirm they can effectively handle the data formats, structures, and volumes involved in your migration process. Additionally, consider the ease of integration with your current IT infrastructure and the ability to support any custom data transformation needs.

 Consider:

• Native ERP migration utilities
• Third-party ETL (Extract, Transform, Load) tools
• Custom scripts for specific data transformation needs

Perform Rigorous Testing

Implement a comprehensive multi-stage testing approach to ensure the integrity and functionality of the migrated data. This approach should include:

• Unit testing of individual data elements
• Integration testing to verify relationships between data
• User acceptance testing involving business stakeholders
• Performance testing to ensure system responsiveness with migrated data

Engage Stakeholders Throughout the Process

Regular communication with key stakeholders ensures everyone is informed about the ERP data migration progress and potential challenges. You don't want to catch anyone out and impact their ability to do their job, so ensuring everyone is on the same page is crucial. It also allows organizations to gather valuable input on data requirements, tailoring the process to meet departmental needs and building stakeholder confidence in the transition.

• Set realistic expectations
• Address concerns promptly
• Gather valuable input on data requirements
• Build confidence in the migration process

Plan for Post-Migration Support

Despite thorough planning, sometimes things do just go wrong! It's important to have a proper support structure to address any issues that may after after migration completion:

• Dedicated support team for data-related queries
• Documentation of common issues and resolutions
• Process for remediation of data discrepancies
