SAS/SHARE Cross-Version Issues, SAS 9.2

Consequences of a Client/Server Upgrade to SAS 9.2


Upgrade: Definition

An upgrade is the process of installing a later version of SAS software over an existing version of SAS software at the customer site (for example, from SAS 8.2 to SAS 9.2). A system manager at your site is responsible for performing the upgrade.

The result of an upgrade can affect the ability of SAS/SHARE clients and servers to connect and share data.


Data Migration

Accessing your data is a primary concern after upgrading to a new version of SAS. If the server (and clients) have been upgraded to SAS 9.2, and you want to make all new I/O engine features available, you can migrate the data to the release that the server runs. For complete details about migration, see http://support.sas.com/rnd/migration.


Access Restrictions Following an Upgrade to SAS 9.2

If you do not migrate your SAS data and applications to the new version of SAS, you will be accessing SAS files and using SAS applications in a cross-version environment. Therefore, it is important to be aware of any restrictions when operating in a cross-version environment. The following tables identify the combinations of SAS/SHARE clients and servers, the SAS version that they run, and their ability for access.
