To upgrade DirectConnect:
Create a backup copy of the *.cfg files available in the $SYBASE/DCO-12_6/install and $SYBASE/DC-12_6 directories.
Shut down all DirectConnect servers.
Install DI Suite 1.1 in the same installation directory as the version from which you are upgrading. For instructions on installing DI Suite, see “Installing DI Suite components”.
In the case of DirectConnect for Oracle (DCO), if you intend to use the same server configurations as the existing one after upgrading, you need not run the DCOConfig script. This script needs to be run only when you define a new server.
During installation, if the installer prompts you with a message that certain files already exists on the system and is newer than the file being installed, and asks you if you want to replace these files, select the No to All option and proceed with the installation.
Make sure DirectConnect has been successfully installed. To check for valid installation, see “Check for a valid installation”.
