Windchill Directory Service Upgrade

As part of my Windchill 9.1 to 10.0 upgrade, WindchillDS must also be upgraded and rehosted. The Windchill Upgrade Guide says to export the LDIF file from the 9.1 server and import it in the 10.0 server. The Guide uses a command prompt export line.

Do I get the same results if I use the GUI export on the 9.1 server and the GUI import on the 10.0 server?
