  • ERROR_SCHEMA_INVALID_KEY code – A message will appear to require an administrator to take action to minimize any possibility of data loss due to changes in the database structure.
  • MAINTENANCE MODE code – A message will appear once the upgrade is in progress and the information screen will change its appearance and inform the audience about the maintenance status.
