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:
setenv OLDSYBASE_ASE ""
This is required if you are using the sqlupgraderes utility to perform your upgrade.
Use either of the following methods to upgrade Adaptive Server:
sqlupgrade – provides an X-Windows or Motif GUI for the upgrade process. See “Using sqlupgrade”.
sqlupgraderes – provides a noninteractive, file-based interface for the upgrade process. sqlupgraderes allows you to upgrade Adaptive Server using a resource file. This is useful for customer sites that want to upgrade many similar servers. See “Using sqlupgraderes”.
