You can upgrade to the Cluster Edition from:
12.5 through 12.5.3 ESD #6
15.0 through 15.0.1 ESD #4
You cannot directly upgrade from 12.5.4 including ESDs nor can you directly downgrade from 15.0.2. If you have any of these versions and want to install the Cluster Edition you must first:
Downgrade from 12.5.4 to 12.5.3 ESD #6 by following the instruction in “Downgrading Adaptive Server 12.5.4.” Downgrade from 15.0.2 to 15.0.1 ESD #4 by following the instructions in “Downgrading from Adaptive Server 15.0.2.”
Once you have completed the downgrade process, you must follow the steps outlined in this chapter for upgrading to the Cluster Edition.
To upgrade from 15.0.1 to the Cluster Edition, use the upgrade procedures described in this manual. For more information on migrating from unsupported version see “Migrating to the Cluster Edition from unsupported editions”.
Only upgrades to and from the same page size are supported. Use bcp to re-create the schema and load data from one page size to another.
Use Adaptive Server plug-in or the sybcluster utility to perform many of the pre-upgrade and upgrade steps for you. You can also upgrade the server manually.
To use Adaptive Server plug-in – go directly to “Upgrading from an earlier version using Adaptive Server plug-in”.
To use sybcluster to upgrade the server – go directly to “Using sybcluster to upgrade to the Cluster Edition”.
To upgrade the server manually – follow the instructions in this and succeeding sections.
See “Migrating to the Cluster Edition” for information about migration.
Manually upgrading Adaptive Server consists of
six processes
Perform pre-upgrade tasks.
Back up your database.
Install the new server into its own installation directory.
You must have both the old installation and the new
installation to perform an upgrade.
Run preupgrade from the Cluster Edition release location.
Each new version of Adaptive Server contains different features that introduce new parameters, commands, reserved words, and so on. For this reason, preupgrade is used for preparing the old server for upgrade.
Run the preupgrade utility against the old servers to update the underlying schema so that their structures are correct for the new server.
You see advisory warnings when configuration parameters
are not set to the default. These do not require any action.
Perform post-upgrade tasks.
