Overview of Migrating Content to SAS 9.2

High-Level SAS Migration Requirements

Migrating SAS 9.1.3 to SAS 9.2, requires the following:

full system migration all at the same time.

All your SAS 9.1.3 content and configuration is migrated to SAS 9.2 at the same time.
the same topology.

Your SAS architecture must continue to be distributed across physical machines in the same fashion. When migrating to SAS 9.2, you must continue to group your SAS components on the same physical machine (or a corresponding machine) as you did in SAS 9.1.3.

Note: You can add new SAS 9.2 products during a migration. Make sure the new product components are contained in your SAS order and deployment plan file.
the same middle tier.

Your SAS middle tier must stay essentially the same. However, you can change your Web application server vendor. In fact, when you migrate, the SAS Deployment Wizard makes the following replacements:
- The JBoss Application Server replaces Apache Tomcat.
- The SAS Content Server replaces Xythos and Apache HTTP WebDAV servers.
the same operating system family.

Your SAS 9.2 components must run on the same operating system family as they did in SAS 9.1.3.

You can migrate within the Windows family (for example, Windows 32-bit to Windows 64-bit) or migrate within the UNIX family (for example, Solaris to HP-UX).

The SAS Migration Utility uses the CPORT and CIMPORT procedures to change file formats when migrating within operating system families. For more information, see The MIGRATE Procedure, The CPORT Procedure, and The CIMPORT Procedure in the Base SAS Procedures Guide.

For more information about post-migration tasks when migrating from one version of an operating system to another, see Overview of Performing Post-migration Tasks.

Note: On UNIX, SAS 9.2 should be installed on a file system that supports large files. (Files that are greater than two GB in size.)
baseline SAS maintenance level: 9.1.3, SP4

Xythos must be at 4.0.48 or later.

Later in this document, you will be instructed to create a migration analysis report for each tier of your SAS 9.1.3 deployment. The major purpose of this report is to help you to identify those SAS components that must be upgraded before you can migrate to SAS 9.2. For more information, see Inventorying Your Current SAS Deployment.
