Moving slowly to new version

I've got my site running at : Concrete5 ( is inside the directory "/site/". I want to move to new version of Concrete5. Is it possible to create a new directory like "/site2/" with new version of concrete5 inside. (I guess I need another database for it ?) : I'd like to move progressively to the new version while keeping the actual site running on
Thanks for your help.

Yes (and yes). This is a good way to do it.

And it works :
the old one (in 5.6) is still alive :

and the new one (in 5.8.1) is starting :

It just requires a second data base
