Hot Topics
- 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.

Migration
Files to Migrate
An early planning task is to discover what existing files you need to carry over to the target SAS®9 installation. To continue using an existing file after you upgrade to SAS®9, you have three choices:
- Migrate the file to SAS®9 format so that you can fully exploit the
capabilities of the software. PROC MIGRATE both changes the file format
and copies or moves the file to the target installation. Some earlier tools
accomplish the same task, but PROC MIGRATE is more efficient
and offers additional features.
- Move the file to the target installation. Moving a file is distinguished
from migrating in that no change is made to the file. You are subject to
compatibility constraints.
- Maintain the source SAS site license, so you can continue processing the file in the earlier release. This is not recommended. SAS prefers that you fully upgrade all your processes so that we can provide the very best product and the very best technical support. In future releases of SAS, compatibility with Version 6 files will be reduced.
The following topics help you identify what files to migrate, what files to move, and how to update syntax.
- Taking Inventory of Files
- enables you to take an inventory of all the different file types that are associated
with SAS and then determine how to migrate them. PROC MIGRATE is featured.
- SAS®9 Compatibility
- explains the basic compatibility for SAS 6, 7, or 8 files in
SAS®9, and vice versa. Most SAS file types are discussed.

Compatibility Calculator.
- Updating SAS Code
- helps you determine whether any existing SAS or SCL syntax needs to be updated for SAS®9.
- Product-Specific Compatibility Issues
- lists cross-release compatibility issues, changes to requirements, and
changes to syntax
for several different SAS products.
- Taking Inventory of Migration Tools
- lists the tools available to move and migrate your data and other files. Or go directly to the PROC MIGRATE Calculator.
