Server Config is unable to connect to an Adaptive Server
that uses named pipe directory service. You must remove named pipe
directory service from the interfaces file before upgrading the
Adaptive Server.
To assist with the upgrade process, Sybase recommends you set the OLDSYBASE, OLDSYBASE_ASE, and OLDSYBASE_OCS environment variables to point to the old installation of Adaptive Server. If you set these environment variable to the old installation of the Adaptive Server, the upgrade utility automatically populates input fields with the correct information as you upgrade.
Set the OLDSYBASE_ASE variable to the SYBASE_ASE appropriate to your older server. If you are upgrading from 12.0 for example, it should be ASE-12_0. If your preupgrade version is earlier than 12.0, specify it as null:
set OLDSYBASE_ASE=""
This is required if you are using sybatch.exe to perform your upgrade.
Install the new Adaptive Server into the same directory as the Adaptive Server you are upgrading.
This section covers the upgrade process, and outlines the following tasks:
Installing version 15.0 software on the target computer. See Chapter 2, “Installing Adaptive Server.”
Upgrading the servers with syconfig or sybatch.
Post-upgrade tasks, including how to enable earlier versions of programs and databases, allowing them to utilize the new version’s functionality.
The installation procedure for Sybase Central and the
Adaptive Server plug-in for Sybase Central has changed. Beginning
with version 12.0, Adaptive Server uses the following locations:
Sybase Central in the x:\Program Files\Sybase\Sybase
Central\win32 directory and Adaptive Server
plug-in for Sybase Central in the %SYBASE% directory.
Earlier versions used the x:\sybtools directory.
The Installer modifies your CLASSPATH, PATH, Profiles, and Registry
entries to these specific new locations.
