Should Site.AllRecentChanges be added to the list of pages to rename / migrate? What pages does the automated approach during installation move? (For some reason I didn't recognize the option during my upgrade installation.)

No for Site.AllRecentChanges. Only four pages are migrated from Site/ to SiteAdmin/: AuthUser, Blocklist, ApprovedUrls, NotifyList. On your wiki you may have any of them or none -- in this case you don't need to do anything. You may also already have the SiteAdmin group, if your previous version was 2.2.0-beta58 (released 2007-07-17) or newer. --Petko November 28, 2009, at 12:25 PM
