Migration for Metadata-Based Deployments(February 2009) The SAS Migration Utility analyzes and prepares your
SAS 9.1.3 deployment for migration. See
SAS
Intelligence Platform: 9.1.3 to 9.2 Migration Guide for a complete guide to planning and execution.
SAS®9 File Features Not Supported in Previous Releases: Details
Long names for variables
are not supported in Version 6.
Encoding attribute
is not supported in Version 6. Version 7 and 8 data sets must be updated
or output in a SAS 9 session to be stamped with an encoding attribute.
(The encoding attribute was supported prior to SAS 9 in China, Korea, and Japan.)
The encoding attribute enables you to, for example, more easily process
multilingual data in a single SAS session with the UTF8 session encoding.
See the topic about
National Language Support (NLS).
Long names for formats and informats
are not supported in Version 6, 7, or 8.
Greater than 32,767 variables
is not supported prior to SAS 9.1.
Suppressed transcoding of a specified variable
is not supported prior to SAS 9.1.
CHECK integrity constraints created in SAS 9.2
are not compatible with earlier releases of SAS. If you add the constraint to
an existing SAS data set or create a SAS data set that includes the constraint,
the data set cannot be accessed by any release prior to SAS 9.2.
sas003 encoding method in SAS 9.2
In SAS 9.2, the PWENCODE procedure introduced the sas003 encoding method.
If you encode a password with the sas003 encoding method,
the data set cannot be accessed by any release prior to SAS 9.2.
linguistic collation with the SORT procedure in SAS 9.2
When you use SORTSEQ=LINGUISTIC with
PROC SORT in SAS 9.2, metadata is stored in the data set header to indicate that the data set was sorted.
Previous releases do not support linguistic collation.
If you use the sorted data set in previous releases, the data set is not shown to be sorted, and the COMPARE procedure might
show differences due to the sort assertion. The data set can be accessed.
