I suspect you'll run into problems ...
EasySync hasn't posted an upgrade recently, and there are numerous reports (in this forum, among other places) about issues. It may work, but you may need to fake out the sync software to think you're still using the older version.
You may want to investigate any one of several other third party solutions which DO support ND7 (Commontime's mNotes, Intellisync, iAnyWhere's Pylon, etc.).
