NetSuite Data Migration Services That Protect the Numbers You Run On
Your ERP is only as trustworthy as the data inside it. A clean go-live, a month-end that ties out, reports your CFO will actually sign off on, all of it traces back to how carefully your data was moved. EPIQ Infotech's certified consultants deliver structured NetSuite data migration services that extract, cleanse, map, validate, and reconcile your data, so the system goes live with information your team trusts on day one.
What are NetSuite data migration services?
NetSuite data migration services are a structured engagement that moves business data, master records like customers, vendors, items, and the chart of accounts, plus open and historical transactions, from legacy systems (QuickBooks, Sage, Microsoft Dynamics, JD Edwards, spreadsheets) into Oracle NetSuite. A disciplined migration follows distinct phases: assessment, data cleansing, field mapping and transformation, test loads in a sandbox, the production load, and reconciliation against source totals. Done well, it preserves financial continuity, minimizes downtime, and gives finance reporting it can trust from go-live.
Migration Is the Highest-Risk Phase of Any ERP Project, and the Most Underestimated
Here's the uncomfortable part most vendors leave out: NetSuite implementations rarely fail on the software. They fail on the data. A configuration gap can be corrected. A workflow can be optimized later. But flawed data, duplicate customers, unbalanced opening entries, transactions pointing at records that were never loaded, quietly undermines reporting, compliance, and operational confidence long after go-live. Industry analyses consistently put data migration at roughly 10–15% of total ERP project effort and budget, and poor data quality remains one of the leading causes of delayed go-lives.
The phrase that has survived decades of ERP projects still holds: garbage in, garbage out. Cleaning and validating data before it enters NetSuite is far cheaper than reconciling a broken general ledger after the business is already running on it.
What We Migrate Into NetSuite
Master Data
Customers, vendors, employees, items and inventory, the chart of accounts, subsidiaries, departments, and locations, deduplicated and standardized before they ever touch your instance.
Open Transactions
Open AR invoices, unpaid AP bills, and open sales and purchase orders, loaded so the business can operate in NetSuite seamlessly from the first day.
Historical & Financial Data
Opening balances, trial-balance tie-outs, and the right depth of transaction history for reporting and audit, without overloading the system with data you'll never use.
Custom Records & Relationships
Custom fields, custom record types, and the master-detail relationships that connect them, mapped to NetSuite's data model and validated for referential integrity.
The EPIQ NetSuite Data Migration Framework
No "lift and shift." Every engagement runs through six sequenced phases, each with a checkpoint your team signs off on before we move to the next.
Assessment & Data Audit
We inventory every legacy source, profile data quality, and define what to migrate, what to archive, and what to leave behind. A NetSuite Health Check is often the fastest way to scope this.
Cleansing & Standardization
Duplicates merged, formats standardized, obsolete records retired, and acceptance criteria agreed upfront, so only clean data moves forward.
Mapping & Transformation
A documented field-by-field mapping from source to NetSuite, with transformation rules for dates, currencies, segments, and mandatory fields, captured in a mapping document your auditors can follow.
Sandbox Test Loads
Trial migrations in a NetSuite sandbox surface mapping errors, constraint violations, and volume issues while they're still cheap to fix, not on go-live weekend.
Production Load & Cutover
A sequenced, monitored load, master data first, then open transactions, run over a controlled cutover window using CSV Import, SuiteScript, SuiteTalk, or iPaaS tools like Celigo and Boomi.
Reconciliation & Sign-Off
Record counts, AR/AP aging, inventory value, and trial balances tied out to the penny against source systems, with an audit package documenting that the numbers match.
How Much History Should You Actually Migrate?
One of the most expensive mistakes in a NetSuite migration is moving everything "just in case." More data means more cost, slower searches, and more to reconcile. Here's how we typically frame the trade-off with finance and operations leaders:
| Approach | Best For | Trade-Off |
|---|---|---|
| Open items + balances only | Fastest, leanest go-lives | History stays in read-only legacy |
| Open items + 1–2 years detail | Most mid-market companies | Balanced effort vs. continuity |
| Full transactional history | Audit / regulatory needs | Highest effort, strongest reporting |

Frequently Asked Questions
How long does a NetSuite data migration take?
Most migrations run four to twelve weeks, depending on data volume, the number of source systems, and how much cleansing is required. The assessment phase is usually complete within one to two weeks and sets a realistic timeline.
Can you migrate data from QuickBooks, Sage, or Microsoft Dynamics?
Yes. We regularly migrate from QuickBooks, Sage, Microsoft Dynamics/GP, JD Edwards, and spreadsheet-based systems, mapping each source to NetSuite's data model and preserving the relationships between records.
What if our data is messy or full of duplicates?
That's expected, and it's why cleansing is a dedicated phase. We profile data quality, merge duplicates, standardize formats, and agree acceptance criteria with you before anything is loaded into NetSuite.
Do you migrate full transaction history or just open items?
Both are options. Many companies load open items plus one to two years of detail, while keeping older records in a read-only archive. If audit or regulatory needs require it, we migrate full history with reconciliation tie-outs.
Is EPIQ Infotech a certified NetSuite partner?
Yes. EPIQ Infotech is an Oracle NetSuite Alliance Partner (since 2013) based in the USA, with 15+ years of ERP experience, 100+ NetSuite projects, and a team of certified consultants and developers.
