ERP Data Migration Services
Move from a legacy system to a new ERP with data you can trust. ESS handles ERP data migration end to end — mapping, cleansing, validation, reconciliation and sign-off — so your IFS, Epicor Prophet 21 or new ERP starts clean and cutover is predictable.
ERP migration is where projects succeed or fail — we make it mapped, validated and reconciled, not a leap of faith.
ERP Migration, De-Risked
An ERP system migration is only as good as the data that lands in it. Bad migrations show up months later as broken reports, wrong balances and lost trust. ESS treats data migration as a discipline in its own right: every field is mapped, every record is profiled and cleansed, every load is reconciled against the source, and your team signs off before anything reaches production.
Backed by proprietary migration tooling and 25+ years of moving data into IFS and Epicor Prophet 21, we make ERP conversion repeatable and predictable — whether you're replacing a legacy ERP, consolidating systems, or moving to the cloud.
What ERP Data Migration Covers
A complete, reconciled migration — not a one-off data dump.
Data Mapping
Map every source field to the target ERP's structures, with transformation rules documented and repeatable.
Profiling & Cleansing
Find and fix duplicates, gaps and bad values before they reach the new system.
Master & Transactional
Customers, vendors, items, BOMs, open orders, balances and the history you need to keep.
Reconciliation
Record counts and control totals tied back to the source so nothing is silently lost.
Validation & Sign-Off
Your team validates in parallel and signs off before anything goes to production.
Legacy & Cloud
Legacy systems, older IFS/Epicor versions, and on-prem to cloud conversions.
Tooling and Discipline That Make Cutover Predictable
We've built proprietary tooling and a repeatable methodology specifically for ERP data migration. That means faster mock-load cycles, fewer surprises at cutover, and reconciliation evidence you can hand to auditors.

ERP Data Migration — FAQ
What is ERP data migration?
ERP data migration is the process of moving your master and transactional data — customers, vendors, items, BOMs, open orders, balances, history — from a legacy system into a new ERP. Done well it includes mapping, cleansing, transformation, validation, reconciliation and a formal sign-off, so the new system starts with trustworthy data.
How long does an ERP migration take?
It depends on data volume, the number of source systems and data quality. ESS de-risks the timeline with proprietary migration tooling, repeatable mock-load cycles and parallel validation, so cutover is predictable rather than a leap of faith.
How do you make sure migrated data is correct?
Every migration runs through profiling and cleansing, automated transformation rules, reconciliation reports that tie record counts and control totals back to the source, and a validation/sign-off step with your team before go-live — nothing moves to production unverified.
Can you migrate from any legacy system?
Yes — legacy ERPs, older versions of IFS and Epicor, homegrown databases, spreadsheets and third-party systems. We map each source to the target ERP's structures and handle the transformation and validation in between.
Do you migrate to the cloud?
Yes. We handle on-premises to cloud ERP migrations (including IFS Apps 10 to IFS Cloud) as well as system-to-system conversions, with the same mapping, validation and reconciliation discipline.
What ERPs do you migrate to?
Most often IFS and Epicor Prophet 21, where we have deep product expertise, but our migration methodology and tooling apply when moving to any modern ERP. For IFS-specific migration, see our IFS data migration page.
