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.

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.

• 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.
• Considerations for Component Integration Services
  If you have both a local and a remote server running on SAP ASE version 15.x and are upgrading both of them to version 16.0, upgrade the local server first. If you plan to upgrade one server but not the other, upgrade the local server.
• Preparing to Upgrade
  Use the syconfig.exe and sybatch.exe utilities to upgrade SAP ASE versions earlier than 16.0.
• Changes in SAP ASE Directories
  The directory structures for SAP ASE installations differ, depending on version.
• Preupgrade Tasks
  To ensure a successful upgrade, review and perform preparatory tasks as necessary. Depending on the old server configuration, you may not need to perform all preparatory tasks.
• Upgrade to SAP ASE 16.0
  If you are performing a major upgrade from a version earlier than 16.x, you are ready to upgrade SAP ASE after you successfully run the preupgrade utility.
• Postupgrade Tasks
  After you have upgraded, make sure your new SAP ASE server is up and running.
• Migrate
  You can migrate from 32-bit to 64-bit versions on different computers or partitions.
• SAP ASE Components and Related Products
  After you finish upgrading SAP ASE, upgrade its components and related products.
