WordPress MU

Hello,

I've recently installed wp-mu 1.2.1 and some users already have filled some blogs.

But i now want to switch url styles to "http://blogname.blogs.mydomain.ext"

So..

First, i've read about editing the config table of each blog's to modify their url

Second i've read about adding some rewrite rules to .htaccess (here : http://mu.wordpress.org/forums/topic.php?id=917 )

But is there an automated step via the main admin gui to do so (altho couldn't find any - i might be blind tho)

Or are the two steps i mentioned enough to complete the migration ?

No, got to do it manually. Best bet would be to export out the database and do a search and replace on all of teh URLs in my opinion.

Ok, thanks for the infos, i'll soon try
Altho maybe the "don't worry you can't revert that" or whatever text could be removed from the install ? ;p
