I have recently built a site, schaeferny.com. It uses the last EE version before 2. It has a lot of functionality using modules both from EE and 3rd parties like solstice and Boiklink. They include forum, image gallery with user gallery creation and upload and delete, video gallery with user access from Youtube, music player etc.
I want to replicate this site in another domain. Can I just install EE and and copy over the files? Are there known issues I will run into?
