 * Hi,
 * I want to migrate my WordPress 3.0.1 to WordPress MU 3.0.1
    Note that my WEB 
   provider (PHPNUX) doesn’t allow DNS WILDCARDS. So I can’t use Sub-Domains sites…
   Anyway, I can configure it for Sub-Directories sites like : [http://example.com/site1](http://example.com/site1)
 * So I have followed the process here : [http://codex.wordpress.org/Create_A_Network](http://codex.wordpress.org/Create_A_Network)
   
   I have activated Network features using appropriate line in WP-CONFIG.PHP, modified.
   HTACCESS file, finally activated my Network. BUT, the process inform us with 
   the below :
 * > You cannot choose Sub-directory Install in the following cases :
   >  If your existing
   > WordPress installation has been set up for more than a month, due to issues
   > with existing permalinks. (This problem will be fixed in a future version.)
 * I’m in this case.
    **Is there a way around this ? without breaking existing Perma-
   links !**

 * Yes and no.
 * Yes you can override it. Just set it up with subdomains for now, but before you
   do anything tricksy, go back into wp-config.php and change
    `define( 'SUBDOMAIN_INSTALL',
   true );` to `define( 'SUBDOMAIN_INSTALL', false );`
 * As for breaking thing … well. The reason it breaks things (or CAN break things)
   is that it really depends on your setup.
 * If your current blog is set to use URLs like domain.com/postname, then any time
   a new sub-site has the same name as a post, bad things will happen. And even 
   if you don’t, PAGES will use the URL domain.com/pagename, and they can cause 
   conflicts.
 * It’s not a huge risk, just something you need to be aware of and prepared for.

 * OK, this is what I understood.
 * I’ve just to replace :
    `define( 'SUBDOMAIN_INSTALL', true );` by `define( 'SUBDOMAIN_INSTALL',
   false );`
