SPD Server 5.2 uses
architectures that enable features like the ability to support data
tables that contain more than 2 G of observations. The new architectures
provide functionality that today's data marts need, but the current
generation of SPD Server tables use metadata architectures that are
not backward compatible with SPD Server 3.x software.
SPD Server 4.x tables
use architectures that use SAS 9.4 metadata. SPD Server 3.x tables
use architectures that use SAS 8 metadata. These two metadata architectures
are not compatible. However, SPD Server 5.2 provides a conversion
utility SPDSCONV that SPD Server 3.x customers
can use to convert existing tables into SPD Server 4.x format,
which SPD Server 5.2 can read and open. If SPD Server 5.2 modifies
an SPD Server 4.x table, the
table will be saved in SPD Server 5.2 format. The SPDSCONV utility
is designed to be run by the SPD Server Administrator.
To summarize:
-
SPD Server 5.2 can read SPD Server
5.2 and SPD Server 4.x tables.
-
SPD Server 4.x tables
that are modified by SPD Server 5.2 become SPD Server 5.2 tables.
-
SPD Server 3.x and
SPD Server 4.x cannot read
SPD Server 5.2 tables. If you have SPD Server 3.x tables,
you must convert them to SPD Server 4.x tables
before SPD Server 5.2 can read or open the tables.
Note: Before you begin the SPDSCONV
conversion process, back up all images of the SPD Server 3.x data
sets that are to be converted.
