PROC CPORT and PROC CIMPORT Limitations

The disadvantage of using PROC CPORT and PROC CIMPORT is that they 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 only from an earlier version to a later version (for example, from SAS 6 to SAS 9) or 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 more information about the syntax for these procedures, see PROC CPORT and PROC CIMPORT in the Base SAS Procedures Guide .

PROC CPORT and PROC CIMPORT do not support the transport of any type of view or MDDB.
