Abstract
A database migration system and method that provides continuous transaction service during migration. The invention allows minimal transaction service down time during database migration. The active database is copied to a target and updated at least one time. In one preferred embodiment, updating occurs over decreasing time intervals. When the time intervals become sufficiently short, transition to the target server is implemented by queuing transaction requests from the source server and then executing them on the target server.
