Import full or delta extract to the target database
Full imports occur when the administrator of the target server believes that the target server needs to be refreshed.
For example, if the target server loses network connectivity for a significant period because of a network or power failure. Import of FULL extraction data is suggested when a new target server is set up to establish a baseline for the server.
Note: Disabling entity changes during a full import significantly
improves performance.
Delta imports occur if new data is available in the source database since the previous import (Full or Delta).
