I currently have a site that was built with NOF11 (will be upgrading to NOF2015 soon). The site has numerous catalogs for purchasing products and currently directs buyers to a PayPal account.

I am going to be changing to a different PayPal account and need to know if I need to update each catalog individually or is there a way (i.e. editing the HTML code) to update all sites at once.

Thank you for any assistance.
