l assume yes, but what about the conversations and photos within wechat, whats app and skype? l currently have an overfull 5GB icloud, and was going to pay for a sufficiently large icloud to store all on my old iphone 5s. then use my 'new' iphone 6+s to log into the new larger icloud, would all of things in iphone 5s, be transferred to 'new' iphone 6+s ? would it be as 'seamless' with other online storages like google drive , drop box? or is icloud best for iphone?
l am considering sharing the icloud with family members as well who use iphones, so still icloud best?
