NetSuite Migration Services and Data Migration
Moving your records, history and configuration into NetSuite from a legacy system, with reconciliation you can check rather than take on trust.
Migration is a decision about what to keep
Not everything in your old system should come across.
The instinct on a migration is to bring everything. It is usually the wrong instinct. Legacy systems accumulate duplicate customers, part numbers that mean nothing to anyone still working there, and transaction history nobody will query again. Moving all of it faithfully recreates the mess you were trying to leave.
So the first work is deciding what comes across, what gets archived outside NetSuite, and what gets cleaned before it moves. That is a business decision as much as a technical one, and it is worth involving the people who actually use the data rather than settling it purely on technical grounds.
From there it is mapping, cleansing, a sandbox load, and reconciliation against the source system. The reconciliation is the part that matters: you should be able to check that balances, counts and key records agree before the legacy system is switched off, rather than discovering a gap at your first period close in NetSuite.
Migration scope depends on what you are actually moving.
A first migration into NetSuite from a legacy system is a different scope of work from consolidating multiple NetSuite accounts, or moving to a new NetSuite framework while keeping existing integrations running. We scope against what you are actually moving and from where, not a fixed checklist that assumes every migration looks the same.
What migration covers
An end-to-end NetSuite data migration process.
We preserve the value, structure and integrity of your data inside NetSuite, not just move it.
Cleansing & Validation
We remove duplicates, correct errors, and validate records to ensure only accurate, high-quality data is migrated to NetSuite.
Custom Field Handling
We migrate custom fields and records with precision, ensuring nothing is lost, even your most business-specific data points.
Controlled Data Transfer
Transfers run through defined, logged channels so there is a record of what moved and when. Specific handling requirements for sensitive data are agreed with you before migration rather than assumed.
Sandbox Testing
With the right NetSuite migration tools we test data integrity and system performance in a sandbox environment, ensuring everything works as expected before going live.
Post-Migration Review
After go-live, we verify data accuracy, run reports, and resolve any discrepancies for a clean, confident start in NetSuite.

What clients ask before getting started.
Account-specific recommendations require an understanding of the actual business requirement and NetSuite environment.
What is NetSuite data migration?
It is the process of moving data, including records, transactions, history and configuration, from a legacy system or another ERP into NetSuite, with data mapped, cleansed and validated rather than simply copied across.
What data can be migrated to NetSuite?
Common examples include customer and vendor records, transaction history, inventory data, chart of accounts and custom fields. The exact scope depends on what your current system holds and what the business needs preserved.
Can you migrate data between two NetSuite accounts, not just from another system?
Yes. Subsidiary consolidations, account mergers after an acquisition and standalone-to-OneWorld conversions are all NetSuite-to-NetSuite migrations, and they carry their own considerations around configuration, customizations and historical data that a legacy-system migration does not. We scope these separately from a first migration into NetSuite.
Is downtime required during a NetSuite migration?
Migrations are typically staged through sandbox testing and a cutover plan designed to limit disruption, though some coordination window is usually needed around go-live.
What happens to attachments and file records during migration?
Attached files, whether stored against a transaction or a record, need their own migration path since they do not move the same way structured data does. We confirm what your source system holds and where those files need to land in NetSuite before migration starts, rather than discovering missing attachments after go-live.
What happens if data doesn’t match after migration?
Post-migration review compares migrated records against the source system and reconciles any discrepancies before the legacy system is retired.
How is a migration scoped or priced?
We do not publish a fixed rate, since scope depends on data volume, how many custom fields and records are involved, and how much cleansing the source data actually needs. We scope it against an audit of your specific data rather than quote a number before looking at what you have.
