From this section, administrator can export or import data. For data export we must select some entities like data sources, reports, charts and dashboards. The result will be a migration.xml file. There is no need to know which entities are used (referenced) by selected entities. All referenced entities will be automatically exported. Take a look at the following image:
We see that dashboard contains widgets. Widget contains a report or a chart. Report / Chart contains a data source and optionally links through drill-down to other reports or charts. So, by exporting a single dashboard, all entities that are involved will be exported too.
Any migration file can be used by an import process. When import is launched, a backup zip file of the entire repository is done. Any imported entity which has an id found inside repository will be updated. If id is not found, a new entity is created, taking care of name collision.
Migration process must not interfere with repository modification. Because of that, NextReports Server will show a maintenance page when export or import is running:
