I am unable to update my phone to iOS 14

Maybe this link will help. It would help us to better answer the question if we knew which phone you are using.

If your iPhone, iPad or iPod touch won’t update - Apple Support

I got a new iPhone I want to put my Netflix’s on my new one and turn off Netflix’s on old phone ! The apple IDs aren’t the same I can’t even find how to get to my acct.My. Xnew phone says I don’t have a subscription I tried using old Id and. password. but nothing pulled up for my account! I think it’s confusing having two accounts but. I’ve not seen even one !!

Be happy it will not update, the update will make your battery drain to 10% charge in less than 5 minutes
