Magento E-Commerce website move

We have an e-commerce website using Magento that is already in service. We do not need to change anything in this website but a backup copy of website files and database has to be taken and setup in a new domain. After the transfer of files to new domain, need to deactivate few categories and some changes need to be done in categories. Currently this website has IP blocking enabled. User in US only can access the site. But for the website in new domain canada also has to be added in access list. To summarize, the following needs to be done: * Download exiting files and database from exiting website * Transfer exiting files to new diomain without disturbing current site * Make category modification. In the current site there are 4-5 categories but in the new domain only one category will need to be visible * Add IP blocking to allow only canada and USA. Currently only USA is allowed I feel that this job can be done in a week.
