combine SAS 9.2 and SAS 9.3 orders in the same software depot.
When you initially
install SAS 9.3, you are required to create a new software depot.
Before you update an existing
SAS 9.3 installation, you must stop all SAS servers. It is recommended
that you back up all the files in your SAS installation and configuration
directories. Create backups of the installation and configuration
directories for SAS for each machine in your deployment, and use these
backups if you need to restore your previous SAS deployment. For more information,
see Best Practices for Backing Up and Restoring Your SAS Content in SAS Intelligence Platform: System Administration Guide.

release, SAS automatically backs up any file in the SAS installation
directory that will be modified during this update. These backups
are saved in the maintenance directory for each product. The general
format of this directory path is
Here are two examples of these backup directories:
For Base SAS 9.3:
Examples of this path
in Windows environment include
For SAS Web Report Studio 4.3:
If disk space is limited,
then after the maintenance release has been installed, you can use
the SAS Update File Cleanup Utility to remove the backups that SAS
created. This utility must be run under the user ID that was used
to install SAS. For more information about
how to use this utility, see Remove Update Backup Files in SAS Intelligence Platform: Installation and Configuration Guide.
