Cloud-Native Migration · Data Lossless · Zero-Downtime · Compliance-Aligned

Legacy System Migration Services are designed for enterprises "using outdated systems (e.g., legacy SAP/Oracle ERP, on-prem custom software) facing performance bottlenecks or compliance risks", covering cloud-native migration (on-prem to AWS/Azure/GCP), system version upgrades (e.g., SAP ECC to S/4HANA), and cross-platform migration. Unlike simple data transfer, we offer end-to-end services: system assessment → solution design → data migration → function validation → maintenance support. Using incremental migration + parallel operation, we ensure 100% data integrity and zero business downtime, complying with GDPR/CCPA. Completing migration in 2-5 months, it solves pain points like "system lag, data security risks, and inability to support business growth".

1. Core Service Content (Modular & Specific)

• Legacy System Diagnosis: Assemble a tech team to analyze outdated system status (version, architecture, data volume, core function dependencies), delivering Legacy System Assessment Report to identify migration risks (e.g., "historical data format incompatibility", "custom function reconstruction need");
• Migration Goal Confirmation: Align with business needs (e.g., "cloud cost reduction", "GDPR compliance") to define migration direction (cloud-native/version upgrade/cross-platform) and target system selection;
• Solution Development: Deliver Legacy System Migration Proposal, outlining migration steps (e.g., "historical data first, then real-time business data"), rollback plans (system recovery if migration fails) and timelines to ensure business continuity.

2. Data Migration & Function Validation

• Data Processing & Migration:

3. Launch Support & Maintenance

• Switch & Launch: Complete official system switch during low business hours (e.g., weekends) with 7×24 on-site support, resolving switch issues within 1 hour;
• User Training: Conduct 2-3 layered training sessions (admins/operators) for target system differences (e.g., SAP S/4HANA vs ECC interface), delivering *Operation Manual*;
• Long-Term Support: Provide 1 year of free maintenance (solving target system issues, data optimization) and support subsequent iterations (e.g., new business module integration) for stable operation.

4. Target Scenarios

• 1. Cloud-Native Migration: E.g., a manufacturing enterprise migrating on-prem SAP ECC to SAP S/4HANA on AWS, reducing server costs and improving scalability;
• 2. Version Upgrade Scenario: E.g., a retail brand upgrading legacy Oracle CRM to Oracle CX Cloud, gaining real-time customer data analytics and omnichannel support;
• 3. Cross-Platform Migration: E.g., a finance firm migrating Windows Server 2008-based core banking systems to Linux + microservices, enhancing security and compliance with GDPR;
• 4. Legacy Replacement Scenario: E.g., a healthcare provider replacing outdated on-prem patient record systems with cloud-based Epic EHR, ensuring data interoperability and HIPAA compliance.
