If you are keeping the original site and all urls then it's simple enough to do a url forward from your domain registrar's control panel.

Most provide this for free, some charge a small fee.

My most recent experience of doing this was last November and basically it took a week for the big 3 to sort it out and within a 2/3 weeks all the old stuff was gone and all the new were in in the SERPs.
