Upgrade

You can upgrade to Adaptive Server 15.5 from Adaptive Server versions 15.0 through 15.0.3 (except 15.0.1 Cluster Edition and 15.0.3 Cluster Edition).

If you are installing Adaptive Server 15.5 on top of an earlier 15.x version see Installing version 15.5 over an existing 15.x Adaptive Server.

If you need information on recovering from a failed upgrade see Recovering from a failed upgrade.

Note:

Adaptive Server 15.5 is certified for the operating system versions described in the System Requirements section of this document. Adaptive Server 12.5.x is certified for the same operating system versions. Hence, an installation upgrade from 12.5.x release may be made to a 15.x version of Adaptive Server.

Note:

Adaptive Server version 15.5 does not support upgrade from Adaptive Server version 12.5.3a.

Adaptive Server version 15.5 introduces some new system catalogs and some changes to existing catalogs.

The catalog upgrade in 15.5 may affect your existing applications. If you are upgrading, see the Adaptive Server Enterprise New Feature Guide for 15.5 for a complete list of catalogs that are affected.

For a server installation 12.0.x and older, Sybase recommends that you upgrade to version 12.5.4, then upgrade to version 15.5.

You can upgrade Adaptive Server from a 32-bit version to a 64-bit version, but you cannot move from a 64-bit version to a 32-bit version. Likewise, you can upgrade only from an earlier version of Adaptive Server to a more recent version.

Only upgrades to and from the same page size are supported. Changing the server schema from one page size to another is a database migration. See sybmigrate in the Utility Guide for information about migration.
