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.

1. 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.
2. If upgrading from Adaptive Server 12.5:

   setenv OLDSYBASE <old_$SYBASE_directory>
   setenv OLDSYBASE_ASE ASE-12_5

   This is required if you are using the sqlupgraderes utility to perform your upgrade.
3. 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 the Using Sqlupgraderes topic.

• Using Sqlupgrade
  sqlupgrade verifies that the server is eligible for the upgrade. Perform all pre-upgrade tasks before running sqlupgrade.
• Using Sqlupgraderes
  You can upgrade Adaptive Server in noninteractive mode by using values from a resource file that defines the attributes for the server to be upgraded.
• Upgrading Using Sqlupgraderes
  When you have finished editing your resource file, you can run the file using sqlupgraderes.
