User blog comment:JeskaD/Lifestyle Admins: Prepare your Wiki for the New Look/@comment-761251-20101002115203

Some of the steps that JeskaD omitted are these:
 * add the tools you were used to seeing on the sidebar to "My Tools" on the bottom toolbar
 * Adjust the top navigation for your wiki at Mediawiki:wiki-navigation if needed
 * examine all pages to see if they have content that is too wide to fit the allotted 660 pixels; if so, make them more narrow
 * realize that instead of the site notice you now send a community message by editing MediaWiki:Community-messages (I haven't gotten that to work myself yet)
