Use the rs_init utility to configure a new Replication Server and to add databases to your replication system. If you have an existing Replication Server, you can use rs_init to upgrade to a new version or downgrade to a previous version. rs_init is installed with the Sybase software. You can use it interactively or with a resource file.
Refer to the Replication Server Configuration Guide for your platform for complete instructions on using rs_init.
