Gets or sets the change token to use when exporting incremental changes based on changes since the last export.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
This property provides a starting point for retrieving changes when exporting incremental changes. Set this value to the value of CurrentChangeToken, which you saved the last time you ran an export.
Field deletion (fields deleted at the export location since the last export are deleted at the import location) is supported for incremental export/import as long as ExportMethod has a value of ExportChanges and the RetainObjectIdentity property is set to true.
