Data Migration: Your ERP Runs on Your Data.
Most companies going through an ERP project discover too late that no one involved is contractually responsible for their data. The vendor delivers the system. The implementation partner moves what you provide. The quality, structure, and completeness of that data — the single largest risk factor for a successful go-live — sits with you. We take that risk off your team, from legacy assessment through post-go-live validation.
Where ERP Data Migration Projects Go Wrong
Data migration is consistently identified as one of the top three causes of ERP project failure. In most cases, the problems are not technical—they are structural. The following patterns account for the majority of missed go-live dates and post-implementation issues.
Data quality is often underestimated
Legacy systems accumulate duplicates, incomplete records, inconsistent formats, and outdated information over years or decades. Without thorough assessment and cleansing, these issues carry into your new ERP system and undermine reporting, planning, and daily operations.
Responsibility for data quality is unclear
Your software vendor and implementation partner may move the data, but they are typically not responsible for ensuring it is complete, accurate, and ready for the new environment. This gap is one of the most common reasons projects slip.
Data problems appear late
Most issues become visible during the first test loads or reconciliation runs—the point at which timelines are tightest and corrections are most expensive. Structured assessment and validation earlier in the project prevent this.
Multi-site data is more complex than it appears
When customers, suppliers, materials, or products are maintained across multiple locations, business entities, or countries, the same information often exists in different structures and definitions. Consolidating this into a single, reliable source is a project of its own.
Let's Talk About Your ERP Data Migration
Whether you’re still planning, deep in implementation, or fixing what went wrong after go-live, our independent experts help you find the right path forward.
Our ERP Data Migration Services
We cover the full data migration workstream—from initial assessment through post-go-live validation. Services can be engaged individually or as an integrated program, depending on where your project stands.
Legacy Data Assessment
We evaluate the quality, structure, and completeness of your legacy data. The analysis identifies risks, effort, and scope early, so your team can make informed decisions about what to migrate and what to leave behind.
Data Cleansing & Deduplication
We clean, standardize, and consolidate your legacy data. Records are deduplicated, formats are aligned, and gaps are closed before migration begins—ensuring your new ERP system starts with a reliable foundation.
Data Mapping & Transformation
We define how each field, table, and record maps into the target ERP system. Transformation rules are documented, testable, and reviewed with your team before implementation, providing full transparency over what changes and why.
Test Loads & Reconciliation
We run controlled test migrations and reconcile results against your source systems. Issues are identified and resolved during rehearsal cycles, not during your go-live weekend.
Cutover Support
We support your cutover with a defined data migration plan, monitored execution, and reconciliation checkpoints—so nothing is missed under time pressure and the go-live decision is based on evidence.
Post-Go-Live Validation & Recovery
Once live, we validate business-critical data against source systems and support recovery where reports, balances, or operational data do not match expectations.
Move What Matters. Leave What Doesn’t.
One of the most consequential decisions in an ERP data migration is how much historical data to bring across. Most companies overestimate what they actually need—and pay for it in scope, timeline, and post-go-live performance.
Migrating years of transactional history rarely delivers the value teams expect. Historical detail is often better served through archiving, reporting layers, or read-only access to legacy systems. What must move are open transactions, active master records, valid balances, and the historical depth genuinely required for operations, reporting, and compliance.
We help you make this decision structured rather than default:
- Distinguish between what is operationally necessary, what is regulatory, and what is optional
- Identify records that can be archived or accessed through alternative means
- Quantify the effort and risk implications of each scope option
- Document the decision with sign-off from business, IT, and finance stakeholders
The result is a scope your team has actively chosen—not one that grew by default and became a source of delays and cost.
Why Companies Choose enterDATA for ERP Data Migration
Auditable by Design
Every migration decision, mapping rule, and reconciliation result is documented. Your team receives a defensible audit trail that supports internal reviews, external audits, and compliance requirements including SOX and industry-specific regulations.
Independent Oversight of Your Implementation Partner
We work on your side of the project. Measurable quality standards, tracked scope, and clear acceptance criteria give your team greater transparency and help ensure vendors and implementation partners deliver against what was agreed.
Multi-Site and Multi-Entity Experience
We have worked across international groups, US subsidiaries of European companies, and organizations operating multiple business entities. This shapes how we approach complexity, coordination, and cross-border requirements.
100% Vendor-Agnostic
We do not receive commissions, referral fees, or reseller revenue from software vendors or implementation partners. Our recommendations are based on your data, your systems, and your business requirements—not on a preferred platform.

Frequently Asked Questions: Data Migration
Migration timelines depend on the number of source systems, the quality of legacy data, the historical depth in scope, and the complexity of your target ERP. For most mid-market companies, the data workstream spans 3 to 9 months. A two-week Data Readiness Check gives you a defensible estimate before scope is fixed.
Less than most companies initially plan. Open transactions and active master records must move. Historical detail is often better served through archiving or read-only access to legacy systems. We help you distinguish between operational necessity, regulatory requirement, and optional depth—typically reducing scope by 30 to 60 percent without operational impact.
In practice, the responsibility for data quality and readiness sits with your company. Vendors provide the target system. Implementation partners move the data as delivered. Neither is typically contractually accountable for ensuring the data is complete, accurate, and ready for the new environment. This is where independent oversight matters most.
Yes. Post-go-live data recovery is a defined engagement for us. We identify the sources of the discrepancies, reconcile against original data, and put your ERP data back on a reliable footing. Most recoveries begin with a three-week Data Migration Recovery Assessment.
Yes—this is one of the most common ways we are engaged. We do not replace your implementation partner. We provide independent oversight of the data workstream, define measurable quality standards, and ensure the data your partner receives is ready for the new system.
