Domestic Stack Migration Deepens: From Running to Running Well

Early domestic stack migrations aimed at "it installs, it starts, the main flow works". As the scope extends to core business systems, the bar has clearly risen.

Common challenges

• Performance differences — domestic databases behave differently on complex joins and bulk writes, often requiring SQL rewrites and index strategy changes
• Ecosystem compatibility — some third-party components lack domestic-platform builds, requiring substitutes or custom adaptation
• Operations capability — teams unfamiliar with the new stack take noticeably longer to diagnose faults

Our approach

Run baseline stress tests with realistic data volumes and concurrency before migrating. Keep a parallel running period with dual-write consistency checks. Follow up with targeted operations training and a month of on-site support.
