• 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 SAS®9 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.

Migration

Operating Environment Information

Here are some issues that are specific to the operating environment. Discuss these with your IT experts.

• Read about z/OS compatibility issues if you are using that operating environment.
• Under some platforms, communications access methods have changed for SAS/CONNECT and SAS/SHARE software.

Issues that Arise from Changing or Upgrading the operating environment

The following issues can arise when you upgrade or change your operating environment.

• The new MIGRATE procedure can be used to migrate SAS libraries from 32-bit to a 64-bit architecture on UNIX. However, it has not been thoroughly tested for a change in operating environment families. Use the Migration Calculator to find your migration instructions. In cases where you must use conversion procedures such as PROC COPY, you are directed to see Moving and Accessing SAS Files in the SAS online documentation.
  
  
• A new or upgraded operating environment can require the following changes to setup and administration:
  • inventory and replication of environment variables, which can be set with SAS or with the operating environment; see the SAS Companion for your operating environment.
  • new utilities, for example: text editor software, batch job scheduling and executing, batch printing, or a code management system (file versioning might be automatic under your source operating environment but not under your target operating environment).
  • an OS expert for debugging and performance tuning (see the topic about tuning in the Execution stage).
  • upgrade in scripting languages such as Perl, which can necessitate changes to existing scripts.
  • replication of any file structuring or directory structuring.
  • other changes as a result of kernel differences.
  
  
• Consider any compatibility issues between the SAS installation and those areas of your organization that stay on the old operating environment, for example, a company intranet.
  
  
• Your operating environment provider should provide guidance when you upgrade or change operating environment.
