SPD Server 5.1 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 5.1 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 5.1 can read and open. If SPD Server 5.1 modifies
an SPD Server 4.
x table, the
table will be saved in SPD Server 5.1 format. The SPDSCONV utility
is designed to be run by the SPD Server Administrator.
To summarize:
-
SPD Server 5.1 can read SPD Server
5.1 and SPD Server 4.
x tables.
-
SPD Server 4.
x tables
that are modified by SPD Server 5.1 become SPD Server 5.1 tables.
-
SPD Server 3.

SPD Server 4.
x cannot read

x tables,
you must convert them to SPD Server 4.

before SPD Server 5.1 can read or open the tables.
