multiple sites using Acquia slate

Hi all,

I'm new to Drupal and Acquia slate. I am creating multiple sites for a client. I've elected to copy and move the site from domain to domain using "Back Up and Migrate". It seems to work beautifully, except the home page for the new site reflects the banner info of the old site (yet new image shows) and if I change the title and text on the new site, well it changes the title and text on the old site. I think there is probably a quick fix to this. I appreciate any assistance.

Thanks!
