There's actually a lot of similar question and answers but most of them related to transfer from one server to another and from one domain to another.
The thing I want to do is to create a folder "new_version" within existing web-site, setup WordPress to "new_version", fill in the content, make sure that everything is OK and then - delete old version and copy "new_version" to the root folder.
As DB will not be changed and the domain will be the same (just the folder will be changed) - am I able to do something easy to accomplish this?
May be just copy of
new_version folder contents to root web directory? Anything else will be needed?
