After your initial installation of SAS 9.4, you have several opportunities to update your SAS software. These updates could include applying a maintenance release to SAS, applying a product-specific maintenance release, or upgrading to a new product release. Regardless, the process for applying the updates is largely automated by SAS Deployment Wizard.
The information that you need to update or upgrade SAS is provided in the SAS 9.4 Guide to Software Updates.
Here are the types of updates that you can apply to an existing SAS 9.4 deployment:
A SAS 9.4 platform maintenance release
A maintenance release is a collection of updates to SAS products or components. It can include fixes and new functionality. Currently, SAS 9.4M9 is available. For more information about this maintenance release, see Maintenance Release Announcement for SAS 9.4, below.A product-specific maintenance release
SAS products and solutions might ship their own maintenance release.
When you apply a SAS maintenance release or upgrade to a new product release, SAS Deployment Wizard detects SAS software that requires an update.
Your software order might include software that you previously have not licensed at your site.
Before adding any new software to an existing SAS 9.4 deployment, you must use SAS Deployment Wizard to update the current software at your site. After these software updates are complete, you can add the new software. For more information, see "Adding SAS Products" and "Configuring SAS Products" in the SAS Intelligence Platform: Installation and Configuration Guide.
Migration is a process in which your SAS content and configuration from an earlier SAS release, such as SAS 9.3, is upgraded to run in a later SAS release.
For a high-level overview of the migration path to SAS 9.4, see Moving to SAS 9.4 in the SAS® 9.4 Intelligence Platform: Migration Guide. When performed successfully, migration preserves as much of your current content and configuration as possible and minimizes system downtime.
