Upgrading from cart in root

I've got two sties I'm upgrading that I set up the original cart in the root directory. I've got the new versions in a separate folder (shop). How do I now swap them? The instructions for upgrading, which were a big help, assume both the old and site are both in folders.

BACK UP First...

Remove the root install
Move the /shop install(files) to the root
Edit the 2 configure.php files to reflect this change
Possibly get and run the fix cache key module
Thst is about it

Remove the root install

By jsut deleting all the files and directories? I don't recall seeing any 'uninstall' option.

Yes, and why you should backup first

Thank you! And probably a good reason to put it in a folder. No need to delete to old/previous install. What do they say about hind sight?!?
