WordPress MultiSite Domain Change / Domain Mapping Problem

How can this be done correctly?

What files / databases will I have to edit exactly?

In the wp-config.php I have the following entries:

PHP Code:

define ('MULTI-SITE', true);
define ('SUBDOMAIN_INSTALL', false);
$ Base = '/ dev / wordpress /';
define ('DOMAIN_CURRENT_SITE', 'name.server4you.de');
define ('PATH_CURRENT_SITE', '/ dev / wordpress /');
define ('SITE_ID_CURRENT_SITE', 1);
define ('BLOG_ID_CURRENT_SITE', 1);

, and my dev / wordpress / .htaccess looks like this:
PHP Code:

RewriteEngine On
RewriteBase / dev / blog /
RewriteRule ^ index.php $ - [L]

# Uploaded files
RewriteRule ^ ([_0-9a-zA-Z-]+/)? files /(.+) wp-includes/ms-files.php? File = $ 2 [L]

# Add a trailing slash to / wp-admin
RewriteRule ^ ([_0-9a-zA-Z-]+/)? wp-admin $ $ 1WP-admin / [R = 301, L]

RewriteCond% {REQUEST_FILENAME}-f [OR]
RewriteCond% {REQUEST_FILENAME}-d
RewriteRule ^ - [L]
RewriteRule ^ ([_0-9a-zA-Z-wp-]+/)?( (content | admin | includes) .*) $ 2 [L]
RewriteRule ^ ([_0-9a-zA-Z-]+/)?(.*. php) $ $ 2 [L]
RewriteRule. index.php [L]

Database entries, I’d have to modify in the following Dabell by hand:

DEVwp_postmeta
DEVwp_site
DEVwp_options
DEVwp_blogs
DEVwp_usermeta

Since I’ve at least found a direct URL entries.

Yeah and that’s the big problem! 🙁

Seem to me that the only way to get worpdress working on the “LIVE URL” is to setup a new multisite system and integrating the old one?

Think that will be very hard too?!

Backup and Importing the old stuff would lead into similar problems?
