How can I upgrade my 32 bit Amazon EC2 EBS backed instance into 64 bit one?

Unfortunately, like other OS's, I don't think there is a way to upgrade 32 bit to 64 bit. You'll almost certainly need to do a reinstall.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
