Blogger Importer will it keep original website

I have a Blogger website with a custom domain (http://www.abbotkinney1stfridays.com) and want to use the blogger importer plugin to import to a different custom domain (http://www.abbotkinneyfirstfridays.com) .

After importing, will the original domain be intact as a Blogger website with all posts?

There are 600+ posts will it be able to import this many posts?
