Downgrading to an Earlier Version in Existing Directories

You can revert to an earlier Replication Server version in the existing directories if you backed up your earlier version before upgrading to same directories.

  1. Back up the entire set of files and directories under %SYBASE%.
    These contain the current Replication Server version files.
  2. Downgrade Replication Server using the procedure in Downgrading Replication Server.
  3. Back up the Replication Server ERSSD or RSSD after completing the downgrade procedure in step 2.
  4. To overwrite the directory structure under %SYBASE%, restore the files and directories from the backup you made before you upgraded to the current Replication Server version.
  5. Verify that the .cfg, sql.ini, and run_repservername runserver files are configured to run the version of Replication Server you are downgrading to.
  6. If there was replication activity on the upgraded version of Replication Server prior to the downgrade process, verify that you are using the downgraded version of RSSD files, otherwise restore the ERSSD or RSSD from the backup you have made in step 3.
    If you use an ERSSD, copy the dbfile, translog, errorlog, and backup directories to the corresponding locations. If you use SAMPLE_RS, copy all files and directories under %SYBASE%\REP-15_5\samp_repserver to the corresponding locations.
  7. Set the relevant environment variables in the SYBASE.env file.
    See Environment Variables on Windows in the Replication Server Installation Guide.
  8. Start the downgraded Replication Server version with the runserver file.
    See Runserver File in the Replication Server Configuration Guide for Windows.
