Move uses a two-step process to migrate data: an Extract step
and an Insert step.
- The Extract step copies data from one or more related
tables in one or more database instances to an external file called
an Extract File.
- The Insert step copies data from the Extract File
to one or more destination databases. The destination tables may or
may not reside in the same database as the source tables. If the destination
tables do not exist, Move generates the SQL to create the tables.
