Say I have 4 WordPress sites running on 4 separate installations on folders of the root:
I have site.com, and then site.com/this (Separate Install) , site.com/that (Separate install) sitecom/theother (Separate install).
Now I want to move the 3 sites installed on folders under the installation that is running on the root and still keep the same URLs.
My initial thought was to
*backup the other 3 sites,
*delete the installations,
*Enable multisite functions on the main installation for folders (not subdomains)
*install the themes on the main installation
*Make the 3 new blogs on the main installation with the corresponding themes and upload the content to each.
Does this sound like the way to go, or does anyone have a better way to proceed?
