Adaptive Server Upgrades

You can upgrade to Adaptive Server 15.7 from Adaptive Server versions 15.0 through 15.0.3, with the exception of versions 15.0.1 and 15.0.3 of the Cluster Edition.

You can upgrade from a 32-bit version to a 64-bit version, but you can neither upgrade nor move from a 64-bit to a 32-bit:

If your server has replicated databases, consult the Replication Server Configuration Guide before starting the preupgrade 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 for information about sybmigrate.

Adaptive Server version 15.7 includes both new and changed system catalogs that may affect your existing applications. See the Adaptive Server Enterprise New Feature Guide for a complete list.

Sybase recommends that you do not use the new features offered in Adaptive Server version 15.7 until you are committed to staying with 15.7.

• Upgrade Considerations for Component Integration Services
  If you have both a local and a remote server running on an Adaptive Server version 15.x and are upgrading both of them to version 15.7, upgrade the local server first. If you only plan to upgrade one server but not the other, upgrade the local server.
• Preparing to Upgrade
  Before you upgrade, run the preupgrade utility. You must have system administrator privileges to perform an upgrade.
• Performing Preupgrade Tasks
  To ensure a successful upgrade, review and perform the preupgrade tasks as necessary. Depending on the old server configuration, you may not need to perform all preupgrade tasks.
• Upgrade to Adaptive Server 15.7
  After you successfully run the preupgrade utility, you are ready to upgrade Adaptive Server.
• Postupgrade Tasks
  After you have upgraded, make sure your new Adaptive Server is up and running.
• Migrating from 32-Bit to 64-Bit Versions on Different Computers
  There are three ways to migrate data on different computers.
