Upgrading to Adaptive Server 15.5

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.

Note:

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.

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.
