No, BlogVault migrates your site intelligently, so you have the least hassle possible.
There are a couple of things you will have to take care of so that BlogVault can move your site to the new destination:

  • You will have to either install WordPress on the destination (or create a database manually on the destination, and a corresponding user).
  • You will also have to keep the FTP details of the destination handy in order for BlogVault to move your site.
