These are the disadvantages
of using PROC CPORT and PROC CIMPORT to move SAS files:
-
PROC CPORT and PROC CIMPORT do
not support the transport of any type of view or MDDB.
-
PROC CPORT and PROC CIMPORT do
not allow file transport from a later version to an earlier version,
which is known as
regressing (for example, from SAS 9 to SAS 6). PROC CPORT and PROC CIMPORT
move files from an earlier version to a later version (for example,
from SAS 6 to SAS 9). These procedures also move files between the
same versions (for example, from one SAS 9 operating environment to
another SAS 9 operating environment).
However, you can move
files between releases of SAS 6 (for example, from SAS 6.12 to SAS
6.08). For details about the syntax for these procedures,
see CPORT Procedure in Base SAS Procedures Guide and
CIMPORT Procedure in Base SAS Procedures Guide.
