Upgrading From an Earlier Version

Follow these general guidelines when you install a new version of SAP Sybase IQ.

Choose an appropriate installation directory. You cannot install SAP Sybase IQ in the same parent directory as an earlier version. Uninstall the version currently installed on your system, or install in a different parent directory.
Upgrade your client tools. Although you can use the current version of the client tools to connect to an earlie server version, some options, tools, and objects may not be available.

Upgrading a Multiplex Database

Before upgrading an existing 15.x multiplex database to SAP Sybase IQ 16.0, you must follow these steps:

Shutdown all multiplex servers.
Start the 15.x coordinator with the -iqmpx_sn 1 server option. This step is required to clear out all multiplex related metadata which can interfere with an upgrade.
Shut down the 15.x server.
Follow the database upgrade steps in the SAP Sybase IQ Migration Guide.
