Background
Under domestic technology mandates, the client's collaboration platform had to migrate to a fully domestic stack within a fixed deadline. The platform ran 62 functional modules and processed over 1,800 official documents a day, with a very narrow cut-over window and zero tolerance for downtime.
Solution
- Gap analysis: mapped every module's dependency on foreign components, with a change list and risk matrix
- Adaptation: compatibility work across domestic server chips, OS, database and middleware
- Migration: 2.4 TB of historical data with pre-validation, dual-write verification and one-click rollback
- Performance: rewrote 37 complex queries for the domestic database, keeping average page response under 1.5 seconds
- Compliance: 68 remediations across authentication, access control and security auditing
Outcomes
- All 62 modules adapted and passed functional regression testing
- Cut-over completed in a single weekend window; normal operations resumed Monday with zero user complaints
- Passed Level 3 cybersecurity protection assessment
- Full migration documentation and operations manual handed over for self-management
