Overwriting a Previous Installation

Replication Server Data Assurance Option 15.7.1 is backwardly compatible with the Replication Server Data Assurance Option 15.6 and 15.7 data structures, but additional considerations apply when you are overwriting an existing installation.

• Existing Files Are Overwritten
  When you upgrade or reinstall Replication Server Data Assurance Option, the installer overwrites most existing files from a previous installation.
• Retain Installation Settings
  The installer reads some existing installation settings, such as instance name and port numbers, but does not read most other settings, such as SySAM license settings.
• Configuration Settings
  During an upgrade or reinstallation, the installer uses the configuration settings from the previous installation.
• New Instance Name
  By default, the installer automatically searches the $SYBASE directory for existing DA installations and uses the configuration values from the valid instance directory that has been most recently modified. You may install another instance into same directory for your upgrade or reinstallation.
