I have moved a content db with a site collection from WSS 3.0 to SharePoint Server 2010 by attaching the content db to the Web application. I then upgraded visualy wise the site collection to SharePoint 2010. I just learned that in SharePoint 2010 a standard team site for example is based on wiki site template which gives you lots of nice features to edit the page.
With the site collection I not have to have the features. For example: I do not have the 'Edit' icon in the ribbon I can simply click on. The Site Asset libary does not exist by default. When I go into edit mode then I see the two web part zones I had in WSS 3.0. etc
My question now is: Is there a way how I can "upgrade" the sites in the site collection so they behave the same as the site was build in SharePoint 2010 or will I have to rebuild the site and move the libaries and lists from the old site to the new one?
