- Updates for SAS 9.2 (March 2008)
See the compatibility calculator to determine whether you need to migrate your libraries to SAS 9.2. Use the PROC MIGRATE calculator to find the right example code for your migration.
- Get a Smarter COMPARE
Validation tools for the MIGRATE procedure now work with CEDA and provide additional details about catalogs, indexes, and integrity constraints.
- Start Planning
See Getting Started for the most efficient pathway through all of the SASŪ9 migration documentation.
- Coexistence
Many SAS®9 products can install side-by-side with SAS 8.2 with very good compatibility. See Peaceful Coexistence: SAS®9 and SAS 8.2 for details.
- Sample Validation SOP
See an example SOP: SAS Installation Qualification / Operational Qualification (PDF) (updated 19 May 2008) for the pharmaceutical industry.

Operating Environments Supported in SAS®9
For exact specifications, see the System Requirements for your operating environment, available from the Install Center.
The table below is for SAS Foundation products, which include "classic" SAS products like Base SAS, SAS/CONNECT, SAS/GRAPH, and so forth. The table might not be correct for some newer Business Intelligence products that have been released on the most popular operating environments first. Check with your SAS sales representative if you are uncertain.
| Operating Environment | SAS Bit Specification |
|---|---|
| AIX | 64-bit1 |
| HP-UX for PA-RISC architecture | 64-bit |
| HP-UX for the Itanium processor family architecture | 64-bit |
| Linux for 32-bit Intel architecture | 32-bit |
| Linux for Itanium-based systems
(not supported for SAS 9.2) | 64-bit |
| Linux for x642 | 64-bit |
| OpenVMS Alpha
(not supported for SAS 9.2) | 64-bit |
| OpenVMS for HP Integrity servers | 64-bit |
| Solaris for SPARC | 64-bit |
| Solaris for x64 | 64-bit |
| Tru64 UNIX
(not supported for SAS 9.2) | 64-bit |
| Windows for 64-bit Itanium-based systems | 64-bit |
| Windows for x643 | 64-bit |
| Windows for 32-bit systems | 32-bit |
| z/OS (OS/390) | 32-bit |
1 Under AIX, SAS®9 can run on a 32-bit or 64-bit kernel. See the System Requirements. The processing and the SAS data files you create are 64-bit, regardless of whether the kernel is 32-bit or 64-bit.
2 Under Linux for x64, you can run 32-bit SAS®9. See the System Requirements. The processing and the SAS data files you create are 32-bit.
3 Under Windows for x64, you can run 32-bit SAS®9. See the System Requirements. The processing and the SAS data files you create are 32-bit.
64-Bit Concerns
The bit specification in the above table refers to the SAS software. In general, 32-bit software applications can run on 64-bit computer architecture.
SAS provides much cross-release compatibility for customers who upgrade to 64-bit SAS and want to continue using SAS files created under the 32-bit release. If these issues concern you, first determine whether they apply to you: See Are My Files Foreign in SAS®9? for the circumstances where an existing file is foreign in SAS®9 (or run the compatibility calculator). Then see Upgrading from a 32-Bit to a 64-Bit Operating Environments for a few issues associated with upgrading your platform and your SAS software to 64-bit.
