SharePoint Import/Export Command for Library with version setting disabled

I have to export a SharePoint library from a site in server A and import it to a library in server B such that only the items that are new or updated are imported to site in server B. While this can be done with "UpdateVersion" parameter set to "ignore" for export command, the problem is we don't have version setting enabled for source or destination library. How can I import only the updated items or new items? Enabling version setting is not an option. If its not possible using export/import is there any other way?
