I've done a little searching and while aspects of what I'd like to know have been addressed, my precise situation doesn't seem to have come up. A week or so ago I decided to finally take the plunge and set up blogs for some domains I've been hanging on to. I create separate installations using regular (non-MU) code (without reading about the new features of 3.0 - whoops). This included separate DBs, etc.
So I came across a post on some "Blogging-Secrets-Of-The-Universe-Revealed" website that a new feature of WP 3.0 is multisite functionality. Great. I figured it was time to just bite the bullet and accost myself with this newfangled technology which would probably make my life simpler - being able to upgrade the WP code once for multiple sites sounds good to me. With the release date being May 2010 (now June??), I decided to sit back and wait before delving into too much of the design of the new domains since I'd be upgrading anyways and there was plenty of stuff to keep me occupied offline until then. That said, I've been taking a look at what might be required to do the install, and I'm not sure what will be required I'd like to prepare.
And finally for the question! How can I integrate a number of already existing installations (blogs/domains) into one Granddad of a installation governing them all? Right now I have one blog that's been around for awhile, but then I have 3 new domains that I recently installed WP with but have made no changes to, so I could delete the installation from if required. I did create separate databases for each. Do I need to get rid of the new DBs? I understand the basics of install, but considering I already have an existing blog, how will that be impacted with 3.0 and using multisite?
Just so this is straight, these are not subdomains. An example would be:
Blah.com - about yoyos
Blahblah.com - about Frisbees
Blahblahblah.com - about bouncy balls
Get the picture? Each a separate name and content unto itself.
Any direction in this endeavor would be greatly appreciated!
Thanks in advance!
