Moving all pages & posts to password protected area.

Hello

I have a wordpress.org site which I would like to archive exactly as it is (pages and all) but in a password protected area, mainly for reference. At present there are a handful of posts spread over a couple of years. There are also four pages with links to other sites, a single about me page and another page which links to previous years, then to posts within that year.

The theme I use is Lightword.

I would like it so when one enters the password protected area, it looks the same as now. Then, I can start on a new blog, fresh pages and posts.

Thanks in advance,
Simon
