ERP-1 Consulting, Implementation & Smooth Switchover (Replacement / Upgrade of Core ERP Business Management System)
With stability, decoupling, and core replacement as the core strategy, achieving full-scale switchover with no user disruption.
Functional Overview
With "stability · decoupling · core replacement" as the core strategy, we provide localization replacement and upgrade implementation services for ERP, from current-state sorting and solution design to full-scale switchover with no user disruption.
Customer Pain Points
International supply chain risks: after being added to the entity list, the supply and maintenance of existing foreign systems face uncertainty, and autonomy and control are urgently needed.
Replacement is difficult: existing systems are deeply used with thousands of integration points, requiring high investment and posing high risks. Peripheral systems are deeply coupled, decoupling is complex, and data migration risks are high.
Historical data migration is complex: often involving dozens of terabytes of data, in-transit transactions are difficult to handle, and switchover time is long.
High business continuity requirements: ERP interruption will affect core businesses such as financial month-end closing, procurement payments, and production.
Lack of mature switchover tools: manual switchover is error-prone, verification cycles are long, and user effort is high.
Solution Advantages
Full-stack autonomy and control: based on Kunpeng chips, Euler OS, and GaussDB, meeting localization compliance requirements.
Extensible architecture: through the Inside/Outside mechanism, supports continuous personalized evolution in the nuclear power industry.
Three-step strategy: stability (ensure business continuity) → decoupling (northbound/southbound/core function decoupling) → core replacement (smooth switchover by waves).
Full-scale switchover with no user disruption: abandon balance initialization, historical data is traceable; incremental pipeline auto-loading compresses switchover time from 72 hours to 8 hours.
ERP companion toolchain: integrated switchover tools (unified switch/diversion/cache, enabling three-way connectivity between old and new) + data migration tools (pre-configured migration packages, full-link visibility and control).
Dual-wheel verification: automatic parallel verification + manual verification, comprehensive validation of total data volume, field content, and document balances, reducing user verification effort by 200+ person-days.
Easy first, difficult later; standard first, special later: ensures business continuity through phased decoupling and sandbox validation; implements by waves according to subsidiary types, with pilots first and gradual full coverage.
