I am also trying to clone a wp site but with no success.
Took a backup of my live wp install (not www facing, it is an Intranet for a windows Domain).. and copied the files from the plugin backup folder.
Built a new server (standalone, no internet & on workgroup) deployed a clean wp install, installed wpmove (manually) and copy pasted the original server’s backup files to the plugins backup folder on the new server.
Successfully ran Restore, but then could not get the site working on the new server.
Theme plugins and content all in the correct folders but get Database Errors when trying to access the site based on the new name i chose.
Will spend some time looking at IIS tonight and will follow this up with actual error messages.. (sorry for not being prepared before posting..)
But if anyone has any suggestions in the mean time…
