How to Migrating Groups using Import / Export Plugin

Hi, we’rie running Openfire server 3.6.0 with about 30-50 pandion clients using the imbedded server. We’re migrating to another server and i want to make it as easy as possible. Can the user import/export plugin move groups too? we have about 6 groups, not much but its still a hassle to have to redo all of this. i noticed that xml file from the export has group left blank. i tested it out today and i cant get it to export it. maybe there is a simpler way. thanks
