I currently have a live site hosted as an Amazon EC2 instance and have been working on a new site (in a development environment) also on an EC2 instance.

The new site is ready to be pushed live but I am unsure how I would approach this.

I am not overly familiar with Amazon as I am picking up from a previous developer who set all the hosting and instances up.

The live and dev sites are running on the following:

Live – www.mydomain.com
Dev – dev-www.mydomain.com
