I am responsible for more than 200 standalone wordpress installations, on the same server and under the same domain, e.g "http://city.domain.se"
The different sites use plugins of their own choice, and themes of their own choice. As you can understand this is not an optimal solution, espcially not when they call me for support...
Now i would like to merge all of the sites into 1 MultiUser installation, with subdomains.
Is this possible? Are there any tools to make the migration process easier? Can you point me to some kind of manual or written instructions?
I would really appreciate some help on this one.
Thanks in advance.
