Convert data from one Drupal 7 site to another Drupal 7 site

I have an existing Drupal 7 website with come content. I am building a new site with a different design. The nodes on the new site are not identical but have many of the same fields. I need someone to import the old data into the new site either using feeds or Drupal Migrate. - The content type is called "business". - The old site has JSON feeds setup with the data. You can use this if it is helpful. Otherwise you can export the data in a format that is easiest for you to work with. - Almost all of the field types are the same. The one field that is not the same needs to be added and all views need to be updated to show the replaced field. - The old site has a second content type called "business_address" that is a child/reference of "business". Most businesses only have one address. Some have multiple. You will need to import these as separate business nodes. The JSON feeds already has this setup. For example the old site could have 2 business nodes, one with one address and the second with three addresses. This should be 4 nodes in the new site. The JSON feed has this as 4 nodes. 1. business 1 - address 1 2. business 2 - address 2a 3. business 2 - address 2b 4. business 2 - address 2c Attached is a mapping of the fields. Some fields on the new site do not exist on the old and some on the old will not be carried over to the new. Anything with +> in the mapping needs to be recreated with the same settings. There are social media fields. It would be great if this could be a field collection where users could enter one or more links. This should be pretty straight forward.
