10 SAP ASE Upgrades

You can upgrade to SAP ASE version 16.0 from versions 12.5.4 or later.

Upgrades are supported only between nonclustered editions of SAP ASE. You cannot upgrade from SAP

Adaptive Server Enterprise

Cluster Edition to a nonclustered edition.

You can upgrade to SAP ASE version 16.0 from versions 12.5.4, 15.0 through 15.7 by executing the upgrade

sequence from the same node on which the database resides. This is a major upgrade, and requires that you

perform preupgrade tasks.

You can upgrade from a 32-bit version to a 64-bit version.

You cannot upgrade to this version of SAP ASE from:

● Version 11.9.x

● Version 12.0.x

If you are running either of these versions, upgrade first to version 12.5.4 before upgrading to version 16.0.

If your server has replicated databases, consult the Replication Server Configuration Guide before starting the

upgrade preparatory 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.

SAP ASE version 16.0 includes both new and changed system catalogs that may affect your existing applications.

See the SAP Adaptive Server Enterprise New Feature Guide for a complete list.

Caution

Once you upgrade to SAP ASE 16.0, you cannot revert back to an earlier version.

10.1 Considerations When Upgrading from SAP ASE 15.0.x or

Earlier

A minor change was made to the format of a log record in SAP ASE version 15.5 that introduces an unlikely

possibility for the SAP ASE 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 SAP ASE 15.0.x or earlier to

SAP ASE 15.5.x and later (nonclustered editions). See the following table for all possible combinations of

upgrades.
