In a preservation plan it is possible to migrate objects using external alternatives. To do this, the objects are exported, migrated externally and then re-imported.
Unfortunately it is not possible to configure the export path. Therefore it is also not possible to perform migrations separated by institution. At other places in Rosetta this is already implemented. For example, an export path can be entered when exporting an IE. To enable Rosetta's multi-client capability, it would be necessary to separate by institution when exporting in the Preservation Plan.
