The core of Revo is really, really different from that of Evo. You won't be able to simply "upgrade" like that; it cannot use anything from an Evo installation. Any upgrade installation expects to find its config.inc.php file in a specific location, and in the case of Revo that is not manager/includes/ as it is with Evo. An Evo config.inc.php file won't work, anyway.
The /revo/ subdirectory should have only a new Revo installation. You'll then be able to simply copy/paste your templates (changing all the MODx tags from Evo to Revo), then copy/paste your resources and chunks, and any custom snippets. The standard MODx snippets will need to be installed using Package Manager.
Revo comes with nothing extra, you'll need to install the extras you want using the Package Manager (in the System menu). I'd start out with Wayfinder, getResources (replaces Ditto), getPage (to provide paging for getResources or any other listing snippet like that), TinyMCE, FormIt (quite different from eForm, it does not generate the form but works on a regular HTML form in your content) and SimpleSearch. I also always recommend MIGx, for the most amazingly useful customized TVs, as I can't imagine creating any site without it, but that's just my opinion
You'll need to spend time with the rtfm documentation pages for these, as in most cases they work somewhat differently than their Evo counterparts.
You can, of course, copy all of your original site's supporting files such as images, .css and .js files to the same locations in the revo installation. In all of my sites these are put in the assets folder, just as they are for Evo sites, but they can go anywhere you like, as long as the links to them in your HTML are correct.
Provisioner may very well work in your case. I've never been able to get it to work at all, but that's just my relatively brief experience with it.

The Revo analog to ManagerManager is known as "Form Customization", and for the most part (at least for resource editing and creation) is built-in.

There is no equivalent for QuickManager; the closest is called QuickBar and has a similar menu bar that opens the proper page in the Manager for editing or creating resources. No fancy AJAX-based overlay editing, though.
