Data Migration Service
Lossless migration across platforms, systems and databases — plus cloud onboarding. Fast full loads with real-time CDC incremental sync compress the business downtime window to minutes; the non-intrusive architecture needs zero agents on the source.
Full load running, increments chasing —
business stays online
High-speed full load and real-time CDC increments run in parallel; cutover is just one final catch-up.
Six capabilities behind lossless migration
Fast full load + live increments
High-speed parallel load of existing data while CDC captures changes in real time — business runs as usual during migration; cutover only catches up the final increment.
Non-intrusive architecture
No agents installed on the source; log-level capture leaves the production system unmodified and its performance unaffected.
Heterogeneous database migration
Migration between Oracle, SQL Server, MySQL, PostgreSQL and domestic databases such as Dameng, KingbaseES and OceanBase, with automatic object and type conversion.
Cross-platform & cloud onboarding
System-level migration between physical machines, virtualization platforms and clouds (P2V / V2V / to-cloud), plus whole data-center relocation.
Data consistency verification
Automatic object- and row-level comparison after migration with a written verification report — inconsistencies have nowhere to hide.
Click-through B/S operation
Fully graphical wizards — no scripts, no command line — with live visibility of progress and throughput.
How it works: rehearse first, cut over with a rollback
Data Migration Service
Does migration require downtime?
Business runs as usual during the full load and incremental sync; only the final cutover needs a brief pause to catch up the last increment and switch — typically a minutes-level window.
Which databases and platforms are supported?
Mainstream commercial and open-source databases (Oracle, SQL Server, MySQL, PostgreSQL and more) plus domestic databases such as Dameng, KingbaseES and OceanBase; operating systems span Windows, Linux and domestic platforms.
How do you guarantee nothing is lost or corrupted?
Automatic object- and row-level comparison after the full load; incremental sync supports resume-from-breakpoint and conflict detection; verification runs before and after cutover with a written report.
Can you handle domestic-stack (Xinchuang) replacement?
It's one of our most common scenarios: heterogeneous migration from Oracle and other commercial databases to domestic ones, including object conversion, SQL compatibility assessment and performance validation.
Data Recovery Service
Lost data can be brought back. MeiTian's recovery labs combine world-class equipment with patented in-house technology — 365-day 7×24 emergency response, on-site service and strict confidentiality, with critical data rescued for tens of thousands of organizations.
