Prerna - From my experience, unless internal IDs are not being modified in the import package, no/few change/impact will occur for impacted objects (master, iterations and links).
My advice would be to first switch IXB to the PLM_FORMAT (wt.ixb.export.formatType=PLM_FORMAT in wt.properties) and to export/import your objects using this format. It is much more easy (anc convenient) to have a look inside the unique plm.xml file which is resulting from the export using this specific PLM_FORMAT. Then you can notice that each and every object is exported (part, epmdoc and links).
If you wish to apply for a change on the same system as the one which was used for export, you may need to change the internal IDs (for the next import). When considering another Windchill system where no existing object is being created, the import will complete successfully if no conflict is found using those internal IDs.
IMHO It is quite easy to create a dataset and export/delete/import this dataset in order to verify that all objects are being imported successfully. If you wish to create the WTPart first, the import will consolidate remaining objects. However, you need to consider an ID match or change process according to which operation you need to conduct when using a partial dataset to be consolidated through export/import (IXB).
