I am currently in the process of redesigning a successful business website.  First I will be moving the site to a new web host.  Once it is up and running I will begin porting the site into Joomla.Are their any considerations that I need to take into account to keep our rankings where they are?  My goal is to also improve our rank as quickly as possible.
