SAS/SHARE Cross-Version Issues, 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.
Version of SAS/SHARE | SAS/SHARE Client to Server Access Restrictions after an Upgrade from One SAS Release to Another SAS Release | ||
|
SAS 6 to SAS 8 | SAS 6 to SAS 9 | SAS 8 to SAS 9 |
SAS 6 | Yes1 | No2 | No2 |
SAS 8 | Yes1 | Yes1 | Yes1 |
SAS 9 | Required3 | Required3 | Yes1 |
1
Yes. After SAS has been upgraded, the client and server can connect
and exchange data.
2 No. After SAS has been upgraded, the client and server cannot connect. 3 Required. If SAS is not upgraded, the SAS application cannot run. |
Some example results of a SAS/SHARE server upgrade are:
If a SAS/SHARE server is upgraded from SAS 6 to SAS 9.2, a SAS/SHARE client that runs SAS 6 cannot access the SAS/SHARE server.
If a SAS/SHARE client that runs SAS 9.2 and uses applications that are written in SAS 9.2 wants to access a SAS/SHARE server that runs SAS 6, the SAS 6 SAS/SHARE server must be upgraded to SAS 9.2. If the SAS/SHARE server is not upgraded, the SAS/SHARE client's SAS 9.2 applications cannot run.
Some example results of a SAS/SHARE client upgrade are:
If a SAS/SHARE client is upgraded from SAS 8 to SAS 9.2, a SAS/SHARE server that runs SAS 9.2 can be accessed by the SAS/SHARE client.
If a SAS/SHARE client that runs SAS 6 wants to access a SAS/SHARE server that runs SAS 9.2 and uses applications that are written in SAS 9.2, the SAS 6 SAS/SHARE client must be upgraded to SAS 9.2. If the SAS/SHARE client is not upgraded, the SAS/SHARE server's SAS 9.2 applications cannot run on the client.
