Using SAS/SHARE Software

Migration and Cross-Version Compatibility (SAS 6 through SAS 9.2)

Accessing your data is a primary concern when migrating to a new version of SAS. If the server (and clients) have been upgraded to SAS 9.2, and you want the SAS data and SAS applications to run at the same level as the server and clients, you can migrate the data to the version that the server runs. For complete details about migration, see http://support.sas.com/rnd/migration.

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.

Note: SAS 9.2 has many of the same features as Version 8, but a SAS 9.2 client cannot access a SAS 6 server, and a SAS 6 client cannot access a SAS 9.2 server. Because SAS 8 can communicate with both SAS 6 and SAS 9.2, SAS 8 serves as the intermediate release. [cautionend]

Access to data depends on the following:

the SAS data object being accessed (library, file, view, or catalog).
the version and release of SAS being used (SAS 6 through SAS 9.2) to create the data that is being accessed or to develop the client application.
the version and release of SAS being used by the client session or by the server session.
