How to Overcome Data Migration Challenges in ERP Upgrades

Upgrading your ERP system is one of the most critical steps in modernising business operations. But while companies focus heavily on selecting the right platform—whether it’s Microsoft Dynamics 365, SAP, or Oracle—the biggest risk often lies not in the software itself, but in migrating the data.

According to multiple ERP implementation reports, almost 50% of ERP failures are directly linked to poorly handled data migration. When upgrading from legacy systems such as GP, NAV, AX, Sage, or on-premise ERPs to modern cloud solutions, businesses frequently encounter challenges like inconsistent data, missing records, duplicate entries, and compliance risks.

This is where choosing the right Microsoft Dynamics 365 Partner in UK, along with professional ERP Migration Services in UK, becomes crucial. A successful migration isn’t only about moving data—it’s about ensuring accuracy, structure, integrity, and usability in the new system.

Why Data Migration Is the Most Critical Phase in an ERP Upgrade

Many businesses assume that migrating data is just a technical export-import task. But in reality, data migration is a strategic and business-first decision. It influences:

• Reporting accuracy
• Financial audit readiness
• Supply chain continuity
• Customer experience
• Compliance & regulatory trust

If inaccurate or incomplete data enters the new ERP system, the entire business can face disruption post-go-live.

Common Data Migration Challenges in ERP Upgrades

1. Poor Data Quality in Legacy Systems

Over time, old ERP systems accumulate:

• Duplicate customer/vendor records
• Outdated pricing or contact details
• Inactive items or accounts
• Incomplete fields due to manual entries

Solution:
Before migrating, perform data profiling and cleansing. Categorise data into:

2. Unclear Scope of What Data to Migrate

Many businesses try to move all historical data, leading to delays and performance issues in the new ERP.

Solution:
Follow the “Minimal Viable Data (MVD)” strategy:

• Migrate only relevant and operationally critical records
• Keep older data in a separate data warehouse for reporting

3. Complex Field Mapping Between Old and New Systems

Legacy ERPs may use different terminology. For example:

Solution:
Develop a data mapping matrix and validate it with functional teams—not just IT.

4. Compliance and Security Concerns

When transferring financial or customer data, GDPR, HMRC, and ISO compliance must be maintained.

Solution:
Work with a Microsoft Dynamics 365 Partner in UK that follows ISO and SOC-compliant frameworks and ensures encrypted migration pipelines.

5. Lack of Testing Before Go-Live

Many companies move directly to live migration without proper trial runs, leading to post-launch issues like missing records or broken relationships.

Solution:
Perform multiple mock migrations, including:

• Sample dataset load
• End-to-end transaction tests
• User acceptance testing (UAT)

FAQs on Data Migration in ERP Upgrades

Q 1. How long does an ERP data migration take?

Ans: Typically between 6 to 16 weeks, depending on data volume, quality, and system complexity.

Ans: Not necessarily. A hybrid model is ideal—migrate recent and active data, while storing older records separately for audit access.

Ans: Yes. Tools like Kingsway Soft, Data Export Service, Azure Data Factory, or Microsoft’s Data Migration Framework can automate most stages.
