I'm new to WordPress. I designed my current website - http://www.nexusstor.com using Joomla. It is being hosted at a company called CloudAccess.net. I want to completely redesign the website using WordPress and have it hosted at Dreamhost. However, I want to avoid downtime if possible. When I put in my domain name at BlueHost, should I use another domain name, and then when I'm done with my website using WordPress then switch the Domain Names to point to BlueHost.
I figure it will take me about a month to develop my new site, but want to avoid downtime of my current site.
Any feedback would be greatly appreciated!
