To revert to an earlier software version after the site version or system version for a Replication Server has been set to the new version, you must reinstall the Replication Server.
If you plan to downgrade in a directory other than the existing Sybase version directory, make sure that the interfaces file is accessible.
If necessary, downgrade the RSSD for each Replication Server you are downgrading. You must downgrade the RSSD using the pre-downgrade—that is, the most recent—version of rs_init.
