iPhone 6 plus to a iPhone 7 plus

Hi Sierra,

If the sole purpose of doing the swap is to make your phone look like iPhone 7+ then yes and no. You can't stick an iPhone 6+ mobo into iphone 7+. Instead you need to head over to sites like aliexpress and buy a lookalike housing. There are plenty of those out there and will make your phone look like a newer model. For example this one here to make your 6 plus look like an iPhone 8 plus (please note I do not know the quality of the housing nor how good of a bit it'll be, all i did was search iphone 6 housing):
