10.2 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.

SAP does not certify that Component Integration Services running on earlier versions of SAP ASE can connect to

later versions. You may encounter errors if an earlier version of SAP ASE maps a proxy table to a later version and

if the remote table uses functionality that is unavailable in the earlier version.

SAP certifies that each version of SAP ASE connects to earlier versions through Component Integration Services.

Component Integration Services is tested and certified to connect to earlier versions of SAP ASE.

10.3 Preparing to Upgrade

Use the preupgrade, upgrade, sqlupgrade, and sqlupgraderes utilities to upgrade SAP ASE versions earlier

than 16.0.

Prerequisites

Caution

Since it is not possible to downgrade once you upgrade to SAP ASE 16.0, make sure to back up all databases,

including master and other system databases, before beginning the upgrade process.

Context

To perform an upgrade to SAP ASE version 16.0, run the preupgrade utility. You must have system

administrator privileges to perform an upgrade.

Each new server version contains features that introduce parameters, commands, reserved words, and so on. The

preupgrade utility prepares the old server by making sure all necessary directories and settings are correct for

the upgrade. When running the preupgrade utility, manually stop and start the server. You need not start the

server before running the sqlupgrade upgrade utility; the utility starts the server when needed.

If you are upgrading from:

● Version 12.5.4 with cache bindings on sybsystemdb – drop the cache bindings for sybsystemdb that are

bound to a user-defined cache before you run the preupgrade utility.

● Earlier than version 16.x but later than 12.5.4 – from the SAP ASE 16.0 installation directory, use the

preupgrade utility to perform the preupgrade checks on the old server. The utility is located in $SYBASE/

ASE-16_0/bin.
