Use the CS Export Doc Classes to export screen (shown below) to select the doc classes (and all documents for that class) to be exported.
Here you can choose which CS document classes will be exported to the target object store. All document classes are selected by default.
NOTE If the restart option has been enabled on the Select Export Content screen then the user will only be able to view the currently selected and unselected document classes but will not be able to change the selections.
Use the CS Export settings worksheet to gather the required information needed to run the CS Export Tool.
NOTE The Doc Classes to export shown will be specific to the library that is being exported.
