Seamless High‑Concurrency Database Migration for Massive Domestic Transformation

This talk outlines the strategic shift toward domestic, high‑performance databases, comparing shared‑everything, shared‑nothing, and shared‑storage architectures, and presents a seven‑step migration framework—including selection, testing, full and incremental sync, application refactoring, dual‑write or middleware switching, and post‑migration observability—to achieve seamless, low‑impact migration of massive, high‑concurrency workloads.
