The ExtraView - ExtraView peer daemon synchronizes items and specific metadata between two ExtraView instances, with specific mappings and filters configured in a configuration file.
This configuration file is part of an ExtraView task.
The synchronization supports all field types stored in the database with item data, including file attachments. Item relationships are also synchronized. The daemon synchronizes specific metadata objects such as list values and allowed values combinations. However, metadata such as field definitions, layouts, rules and other metadata is not synchronized – these objects are the domain of the XML export / import feature.
The feature is fully described in the Extraview - ExtraView Instance Integration section of these guides.
Add the task, then use the above link to configure the integration of two or more ExtraView instances.
