Adaptive Server Upgrades
You can upgrade to Adaptive Server 15.7 from Adaptive Server versions 15.0 through 15.0.3,
with the exception of versions 15.0.1 and 15.0.3 of the Cluster Edition.
You can upgrade to this version of Adaptive Server from:
• Adaptive Server 15.0 through 15.0.3 (but not the 15.0.1 or 15.0.3 of the Cluster Edition) –
to install version 15.7 on top of an earlier 15.x version, see Installing Adaptive Server
Using Binary Overlay on page 86.
• Adaptive Server 12.5.x – to upgrade from Adaptive Server 12.5.4 or earlier, execute the
upgrade sequence from the same node on which the database resides.
You can upgrade from a 32-bit version to a 64-bit version, but you can neither upgrade nor
move from a 64-bit to a 32-bit:
You cannot upgrade to this version of Adaptive Server from:
• Adaptive Server version 12.5.3a
• Adaptive Server version 12.0.x or earlier – Sybase recommends that you first upgrade to
version 12.5.4 before upgrading to version 15.7
If your server has replicated databases, consult the Replication Server Configuration Guide
before starting the preupgrade tasks.
Only upgrades to and from the same page size are supported. Use sybmigrate to re-create the
schema and load data from one page size to another. See the Utility Guide .
Adaptive Server version 15.7 ESD #2 includes both new and changed system catalogs that
may affect your existing applications. See the Adaptive Server Enterprise New Feature Guide
for a complete list. Sybase recommends that you do not use the new features until you are
committed to staying with 15.7.
Upgrading Adaptive Server
A minor change was made to the format of a log record in both the cluster and nonclustered
editions of Adaptive Server 15.5 and later versions.
This change introduces an unlikely possibility for Adaptive Server to misinterpret this
changed log record in cases where the upgraded server contains a database that is the primary
database for replication.
This change should not affect your upgrade process; however, it requires you to strictly follow
some steps when you move from Adaptive Server 15.0.x or earlier to Adaptive Server 15.5.x
