My blog has been hosted by a friend for years. That person is changing their business, so I need to move the blog. I'd like to transfer it to my existing (yet unused) WordPress.com blog.
Several potential issues:
1. My current version (the one hosted elsewhere) is an older version of WP -- how difficult will it be to transfer my old posts into the WP.com blog?
2. I see that I can use my own domain for $7/year - mapping the domain. But is there an additional fee for WP to host the blog?
3. Or is it free if i keep the "wordpress.com" part in my domain name and I have to pay for hosting if I use my own domain name?
