Hi;
I can see at my top level site under Ste Settings > Site Collection Administration > Visual Upgrade reveals the following dialog box.
Looks pretty obviious that this will Visually Upgrade the entire site collection.
I need to upgrade several sub-sites one at a time so I can correct customizations on each sub-site. So when I'm in one of the subsites at Site Settings > Title, Description and Icon the following choice is available:
Maybe I'm reading too much into the description, but it uses the word "sites" (plural). It's not exactly clear what will be upgraded by seledting the third radio button "Update the user interface". Does selecting this radio button apply the Visual Upgrade to only this sub-site? (Anything else I should know before selecting that radio button?)
Thanks for your help!!
