Migration Prep Checklist
Move all "binary" files (PDFs, Office docs, images, etc) that may be scattered in different folders of your site to the /docs and /pics folder of your current site.
DO NOT move folders, .pcf, or .inc files, as that will disrupt your current site.
Switch to one column
Review each page on your site. If any of them use the Two- or Three Column layout option, they will need to be switched to the One Column layout in the Page Parameters of the page.
Attend a training session to learn how the new features work.
