SAS/CONNECT Cross-Version Issues

Accessing Catalogs

There are limitations and restrictions when accessing catalogs in a cross-version environment.

CAUTION:: A SAS 9 or SAS 8 SAS session cannot read SAS 6 catalogs on AIX/RS6000.
Use the CPORT and CIMPORT procedures to migrate SAS 6 catalogs into a SAS 9 or SAS 8 environment on AIX.

SAS 8 (or later) catalog entry types (alphabetized horizontally) that are compatible with SAS 6 include:

This table summarizes the limitations of a SAS 6 client that accesses catalogs on a SAS 8 (or later) server in a cross-version environment.

Limitations for Accessing Catalogs on SAS 8 (or Later) from SAS 6
SAS/CONNECT Service	SAS 6 Client Connecting to SAS 9 Server	SAS 6 Client Connecting to SAS 9 Server
Remote Library Services	No access is permitted between a SAS 9 client and a SAS 6 server.	A SAS 6 client can read a SAS 6 catalog on a SAS 8 server. A SAS 6 client can read, write, and update a SAS 8 catalog that does not contain new features.
Data Transfer Services	A SAS 6 client can upload a SAS 6 catalog to a SAS 9 or SAS 8 server. The uploaded catalog is converted to SAS 9 or SAS 8 format. A SAS 6 client can download a SAS 9 or SAS 8 catalog if the entry type does not contain new features.
Compute Services	A SAS 6 client can remotely submit a SAS program that references a SAS catalog to a SAS 9 or SAS 8 server.

This table summarizes the limitations of a SAS 8 (or later) client that accesses catalogs on a SAS 6 server in a cross-version environment.

Limitations for Accessing Catalogs on SAS 6 from SAS 8 (or Later)
SAS/CONNECT Service	SAS 9 Client Connecting to a SAS 6 Server	SAS 8 Client Connecting to a SAS 6 Server
Remote Library Services	No access is permitted between a SAS 9 client and a SAS 6 server.	A SAS 8 client can read from and write to a SAS 6 catalog on a SAS 6 server. A SAS 8 client can write a SAS 6 catalog from one SAS 6 library to another SAS 6 library by using PROC COPY.
Data Transfer Services	A SAS 9 or SAS 8 client can download a Version 6 catalog from a SAS 6 server. A SAS 9 or SAS 8 server can upload a SAS 6 catalog from a SAS 9 or Version 8 server if the entry type does not contain new features. A SAS 9 or SAS 8 client cannot create a SAS 6 catalog entry by using PROC UPLOAD.
Compute Services	A SAS 9 or SAS 8 client can remotely submit a SAS program that references a SAS catalog to a SAS 6 server.
