An ERP parallel run is the temporary practice of operating legacy and new systems side-by-side for 14 to 30 days. By confining the double-entry scope to high-risk transactions and reconciling outputs daily, businesses completely eliminate the risk of a day-one system shutdown.

What is an ERP parallel run?
An ERP parallel run is the practice of entering transactions into both your legacy and newly installed systems simultaneously for a bounded period, verifying that database mathematical calculations and outputs match perfectly before a final cutover.
Why is a parallel run critical for factories?
Unplanned system downtime during an ERP migration costs mid-market manufacturing companies an average of $150,000 per hour. Parallel running serves as an operational safety net, keeping logistics and assembly floors moving on legacy systems if the new platform encounters bugs.
Should we run every module in parallel?
No. Duplicating every operational workflow will quickly cause extreme user burnout. The bounded-scope rule dictates that you parallel-run only critical paths like physical inventory movements, stock ledger adjustments, and customer invoicing.
How much does a parallel run phase cost?
Parallel runs and staff training typically require 4 to 9 man-days of consultant support within a standard 25 to 50 man-day deployment. At standard industry rates of ฿7,000 to ฿12,000 per man-day, this planned cost prevents unplanned down-time losses.
When can we safely shut down the old system?
You can initiate the final cutover when the new system achieves a 99.8% reconciliation alignment with the legacy system on core transactional and financial ledgers for 5 consecutive business days without any unresolved data drift.
