ERP Data Migration Checklist

Why Data Migration Deserves Extra Care

In ERP transition projects, most errors don't come from choosing the wrong system — they come from the data migration stage. If inventory, account, product, and customer data carried over from legacy systems is incomplete or inaccurate, the same problems persist in the new ERP. This article offers a checklist for the data migration process.

Preparation Before Migration

Take inventory of existing data

Identify where each type of data currently lives (spreadsheets, legacy software, paper records). This inventory clarifies the scope of what needs to move.

Assign data owners

Identify who's responsible for each dataset (inventory, accounting, HR); they'll validate the data during migration.

Clean data beforehand

Duplicate records, missing fields, and outdated information should be cleaned before migration. Moving dirty data into the new system just carries the problem forward.

Checklist During Data Migration

1. Inventory data: do product codes, units, and current stock quantities match correctly?
2. Accounts: are customer and supplier balances and contact details up to date?
3. Financial history: were opening balances and prior period data transferred correctly?
4. User permissions: who will have access to which module in the new system?
5. Integration points: have e-invoicing, e-commerce, or bank integrations been tested?

Each of these steps aims to prevent operational disruptions after go-live.

Don't Skip the Testing Phase

After data is migrated, it must be tested with sample scenarios before going live. For example, creating an order and checking inventory reduction, invoicing, and reporting end to end surfaces hidden errors early.

What to Monitor After Go-Live

• Compare inventory and financial reports with the old system during the first week
• Collect feedback from users; log interface or data issues quickly
• Keep the old system as a backup for a period, but retire it from active use

Frequently Asked Questions

Who should manage the data migration process?

Ideally, both the technical team and representatives from the departments that own the data should be involved together.

Does operation stop during data migration?

With a well-planned transition and parallel testing, operational disruption can be kept to a minimum.

How long should old data be retained?

It varies by legal and operational needs; keeping it accessible for at least one full fiscal period is generally recommended.

Conclusion

Data migration is the most critical, yet often underestimated, stage of an ERP transition. Following preparation, cleanup, controlled migration, and testing steps in order makes the transition smooth.
