Where Database Alerts & Operators Exist In SQL Server?
That's all in msdb.  Note that the new server must be at exactly the same version to restore a system database.  


  System databases can be restored only from backups that are created on
  the version of SQL Server that the server instance is currently
  running. For example, to restore a system database on a server
  instance that is running on SQL Server 2012 (11.x) SP1, you must use a
  database backup that was created after the server instance was
  upgraded to SQL Server 2012 (11.x) SP1.
