Restoring the server after a failed upgrade

After a failed upgrade, you can restore the server to its original state by restoring the database, installation registry, and the server files from backups.

Before you begin

If you did not back up the installation directory and the registry, you can install the new server and restore only the database. You can keep the data that is already in your database and avoid running the initial import.

Procedure

  1. Stop the server.
  2. Restore the database from a backup.
  3. Replace the installation registry with the backup registry. Copy the .com.zerog.registry.xml backup file to one of the following directories:

    Linux /var/

    Windows C:\Program Files\Zero G Registry\

    If you installed the server as a non-root user, copy the backup file to $HOME/.

  4. Replace the installation directory with the backup directory.
  5. Start the server.
