Transferring from Squarespace 7.0 to 7.1 has been sped up by the Squarewebsites Tools Pro extension. The plus to this extension is also the seamless transfer of blog posts from 7.0 to 7.1 - especially when there are a lot of blogs. We took the client's 7.0 site and did a slight redesign to utilize the new functions available in Squarespace's new 7.1 version.
