Please use caution when installing only the database over an existing site and be sure the correct files correspond with the database. For example, if WordPress 4.6 is on this site and you copy the database to a host that has WordPress 4.8 files then the source code of the files will not be in sync with the database causing possible errors.  If you’re immediately moving the source files with the database then you can ignore this notice. Please use this advanced feature with caution!
