I have an existing and working normal (not multisite) WP installation. Now I've created a new WP MultiSite installation and successfully set up 2 independent sites (both empty).
Now I would like to clone the content from the old site to one of the site within the new multisite installation.
Here is what I've done so far:
- Upgraded the old site to have the very same WP version as the new.
- Installed the very same version theme and plugins on the new site.
- Looked into the DB tables, with no particular result...
I see the DB structure is different for the new site to allow the multisite functionality. So obviously a db export/import will not work. I've also evaluated the possibility to upgrade the old site to be multisite, but that is not possible for various non technical reasons.
What would be the correct solution to move my old site under to a site within the new multisite installation?
