Can't restore iPhone 5 backup to new iPhone 6s?

I bought a new iPhone 6S today and I was hoping to set it up from a previous backup. When I try to use the backup from my iPhone 5, it says the software is too old? Is there a way to transfer my iPhone 5 backup to the iPhone 6S?

(My iPhone 5 has the Apple Beta software installed onto it if that has anything to do with it.)

Youtube videos not loading on iPhone, Macbook or iPad?

Youtube has been working fine for me lately until the other day. Videos are no longer loading and simply the grey loading circles continuously. It first happened on my iPad whilst I was watching videos, they loaded fine until suddenly they just wouldn't load anymore. My phone and laptop were also loading them fine but now no such luck. However, when I clicked on one of Zoella's newest uploads it actually played and that was 20+ minutes so it can't be due to a slow connection. Thinking the problem was no resolved, I went onto another video and the problem came back.
Everything else that requires internet is working smoothly which makes me believe it can't be anything related to my internet as that is working to it's usual speed. Why am I suddenly getting this problem and what can I do? Youtube videos not loading on iPhone, Macbook or iPad

ITunes won't update/install?

I purchased an iPhone 6S today and as I went to connect it to my laptop, I noticed my iTunes software version is out of date (v.12.2.2) and every time I go to install the latest version, I get through the installer, but at the end there's a popup saying 'A later version of Apple Software Update is already installed on this computer.' I rang Apple support, and they said I needed to upgrade to Windows 10 in order to update iTunes, but I can't do this as my computer is linked with my school.

Is upgrading to Windows 10 the only way to update iTunes to 12.3? If not, could someone please guide me to some instructions because I can't figure out a possible solution.

Water Damage + Blue Screen Iphone 6?

So I recently got water in my iPhone 6 via the power port thing… Not much but a little. It froze in the port because I was outside. I went inside picked the ice out of the port. My phone started powering on with the white apple screen multiple times and eventually it stopped. I put it in a bag of rice for 2 days. I tried to charge it and it turned on but then went to a blue screen. It slowly faded to white… I immediately unplugged it. Is my phone shot? Or does it still have a chance?
