If you are upgrading to a newer version, or are reinstalling the current version of Sybase CEP Server or Sybase CEP Studio, first back up the information in your adapters base folder or repository.
By default, both folders are called SybaseC8Repository.
If you plan to reinstall or upgrade in the same folder as the existing installation, make sure that the information you back up includes the following:
Any custom adapter .adl files.
Any user-defined function .udf files.
Any custom library .dll files.
