Convert a Single Domain site to a Multi-Domain

put this Project for " Dswtechnologies/ Steve" This project isn't to start over, it's to finish a website! Most of the WebDesign is already done but some key features are missing, they are the following: - Each domain, will be able to have a different number of languages/translations, now We only have one language per country, - The Calculator that can be found here [login to view URL] , only works for a country, it mus be adapted because different country's will have different Exchange Rates for both Money Exchange and Money Transfer, - The backoffice of the Website has already widgets to change the Exchange Rates for both Money Exchange and Money Transfer, but they are not changing the DB values. - All translation has Spanish that exists associated to a domain, mus be migrated to another domain. - The translations for each domain, must be changeable using the flag of the country
