If you upgrade from
SAS 9.1.3 to SAS 9.3, you do not need to migrate your data sets if
you remain in the same operating environment. If you upgrade across
hosts, such as from a 32-bit to a 64-bit Windows operating environment,
you must migrate your data sets. To migrate your data sets, use CIMPORT,
COPY, or CPORT. For more information, see the
Base SAS Procedures Guide.
Visit the Migration
focus area at
http://support.sas.com/rnd/migration for migration information.
Note: The MIGRATE procedure does
not support the SPD Engine.
