Manually Upgrade Overview

Manually upgrading Adaptive Server consists of six processes.

1. Perform pre-upgrade tasks.
2. Back up your database.
3. Install the new server into its own installation directory.
   Note: You must have both the old installation and the new installation to perform an upgrade.
4. Pick up preupgrade utility from the Cluster Edition release location. Run it against the old servers to update the underlying schema so that their structures are correct for the new server.
   Note: Each new version of Adaptive Server contains different features that introduce new parameters, commands, reserved words, and so on. For this reason, use preupgrade to prepare the old server for an upgrade. However, if you are upgrading from 15.0.1 Cluster Edition or 15.0.3 Cluster Edition to the 15.5 Cluster Edition, you can skip this step.
   Note: You see advisory warnings when configuration parameters are not set to the default. These do not require any action.
5. Perform upgrade tasks.
6. Perform post-upgrade tasks.
