To verify that your system environment is configured correctly:
Verify that the computer on which you plan to upgrade the Sybase products meets the requirements.
Determine whether your server supports an upgrade to Adaptive Server 12.5.x.
Set the environment variables by sourcing the SYBASE.xxx file.
Verify that your operating system is at the proper version level and has all operating system patches needed for Adaptive Server. See the Release Bulletin for your platform.
