I wanted to upgrade from the free server to one of the paid plans, because the server is down for a few times, I need to get a plan which is more reliable.
What steps would I need to do to upgrade with minimal downtime?
The paid plans is found at http://x10hosting.com/premium.php. When you have ordered, you have to creat a ticket in the client area asking for the admins to transfer your free account to your paid.
