 +
 +In older versions, after a configuration modification it was mandatory to follow this procedure to activate the new setup:
 +
 +  * for **data import**: restart the Sprinkler service.
 +  * for **data export**: restart ALL middle tier services (except Sprinkler, not involved by this modification).
 +  ​
 +Starting from version v.0.5.00, this procedure is changed: ​
 +
 +  * for **data import**: new setup will be applied in ~1 minute from the reconfiguration.
 +  * for **data export**: the restart of ALL middle tier services (except Sprinkler, not involved by this modification) will be mandatory only if NEW TABLES are set to be exported; changes like adding, modifying or deleting exportable fields for tables already set for export, or even completely disabling a table from export will be applied in ~1 minute from the reconfiguration.
 +
 +We haven'​t found any official NAV specification about the behavior of observer pattern in case of table schema changes (for exemple, when a new .fob is imported for table set for export): we suggest in this case to follow the most conservatory steps, i.e. to restart all middle tier services on Source database; changes of schema of a table set for import will be handled by standard NAV services Synchronization,​ and no manual procedures are required.
 +  ​
 +//Please be aware that the modification of setup could temporary create a misleading configuration,​ so it's definitively better to change the Data Distribution tables / fields configuration when users are not connected, and finally restart all middle tier services.//
