Yea, it will kill root on the first ota,.. just keep taking them until you reach the last, mk2. it may take a but of time since each ota is about 10 mins to update...
Also I just remembered there is a no wipe Odin file you could use.. if your confortable with Odin it's the fastest method.
once on mk2 just use saferoot to get root back.
