sysconfig.exe cannot connect to
an Adaptive Server that uses a named pipe directory service. You
must remove the 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 12.5 for example, it should be ASE-12_5.
If upgrading from Adaptive Server 12.5:
set OLDSYBASE=<old_$SYBASE_directory> set OLDSYBASE_ASE=ASE-12_5
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 15.0.3 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.
