-Welcome to the umbraco upgrade wizard. This will make sure that you upgrade safely from your old version to <strong>Umbraco version <%=umbraco.GlobalSettings.CurrentVersion %></strong>

-As this is an upgrade, <strong>the wizard might skip steps</strong> that are only needed for new umbraco installations. It might also ask you questions you've already answered once. But do not worry, 
-everything is in order. Click <strong>next</strong> below to begin your upgrade.
