should i just set it up as a new iphone? would that lose all my data from my old phone?
With the gift phone first do set it up as a new iPhone. That will not erase your old data. Then update it to the new iOS and then restore the backup. You may have to erase the gift iphone before restoring. Follow this

However if you still have your old phone and a computer, PC or Mac, back up the old one to the computer and then do the Restore using the computer. That is the best method in my opinion and will not require the erase prior to restoring.
