i was using wordpress mu with a plugin called "multi-site manager" so that i could manage and serve multiple blogs with different domain names via one wpmu install. All i had to do was point the new domain name or sub domain name to my wordpress install folder and it worked. I liked this setup because i could have a testing domain name (beta.site.com) and when it was time to push it live (to site.com), i simply updated the domain name via the multisite manager plugin and would run a link updater plugin so that my local images would show.
It worked perfectly until i upgraded from 2.9 to 3.0.1 The plugin still seems to work but i have lost some important functionality. Now, though everything appears to look ok on the newly created site's homepage, all my nav links to pages/posts and log in links still navigate to the previous testing domain name... and if i was to try to login it would say that "No site defined on this host."
So... what is the best fix (to avoid exporting the old site, importing the new site, activating and configuring all plugins)?
is my multi-site manager plugin buggy for 3.0.1? should i switch over to the "WordPress MU Domain Mapping plugin"? or should i be doing this whole process differently?
