摘要：
Database migration may affect the running of the information system. And the integrity, veracity and business continuity are the difficult problems in the process. We discussed the business continuity in this article. New and old concomitant network environment is constructed at the same time. Voting disk, ocr (Oracle Cluster Registry) and ASM data are migrated stage by stage online. We made zero-downtime database migration and completed the core database migration which supported the teaching, research, IC card and etc. in university. And also it didn't interrupt or affect the information system in the whole process.
