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.

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

  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.)  

  Operating system upgrades are supported. For example, you can upgrade from Windows 2000 to Windows 2003 Server.

  Note:   The SAS automated migration tools do support migrating from Windows 32-bit operating systems to Windows 64-bit operating systems. For more information, see the white paper available at the Migration Focus Area: http://support.sas.com/migration/.  

• baseline SAS maintenance level: 9.1.3, SP4

  Xythos must be at 4.0.48 or later.

  For additional information about specific SAS offerings, refer to: http://support.sas.com/migration/utilitynotes.

  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.
