So you want to change http://www.domain.tld/sitename to http://blogs.domain.tld/sitename or http://sitename.blogs.domain.tld?
I’ve been watching this conversation on Twitter, and I’m a little confused as to what you’re asking.
Are you really just wanting to move your site from http://www.example.org to subdomain.example.org, leaving all of your sites as subdirectories; or are you looking to migrate all of your subdirectory sites to become subdomain sites instead (e.g. move http://www.example.org/subsite to subsite.example.org)? Or, as it seemed to be suggested on Twitter, are you looking for some sort of combination between multiple subdomains and multiple subdirectories?
If the former, it’s really simple; if either of the latter, it’s a bit more complicated.
EDIT – Nevermind, it looks like Eric asked the same question and already got an answer.
In that case, you’re not changing a subfolder installation to a subdomain installation, you’re just moving the domain. It’ll be a little involved, but you’ll need to reset the siteurl and home settings for each site on the network (and can probably do this with a search-and-replace in SQL).
Curtiss – I’m looking for the former.
Heh, I’ve done that a million times when importing my production DB to dev environment 🙂
That’s exactly what you’re doing, Dan; it’s just moving production to a different production, instead of dev => production.
Just watch out for any serialized data.
Now that I’m at a big girl computer….
Just moving from example.com to blogs.example.com isn’t all that difficult, just beware the serialized data.
