WordPress MU

I curently have a blog that uses WP standard script. It has about 1500 posts and about 500 users. I want to know if there is a way to switch/upgrade from the standard WP script to the multiuser script. If yes what is the best way to do it?
Thanks in advance!

This is what I did to move my WP to WPMu:

• BACKUP MY DATABASE
• Configure WP for moving to a subdirectory as it was at the root directory
• Made the move to the subdirectory and confirmed everything still worked.
• Did an Export that is located in Manage > Export
• Installed WPMU
• Did an import into WPMU

Most of everything should copy in fine. The only major snags I ran into were plugins like Counterize because the Export feature only exports core database files and not plugin info. But you can do a database export for those and import them manually in the database one by one and reconfiguring it to match the database scheme of WPMU.

Also here's a hint, WP's database scheme is wp_users, wp_posts, wp_so on... in WPMU, the very first blog (the Site Admin) blog will be wp_1_posts and so forth. So when you are bringing plugin database information, make sure you append the 1 or it won't show up.

Also, did you want the 500 users to them have their own blogs? Cuz there's no easy way to do that.

Have a contest. First 50 moved over get a free gig upgrade. :)

thanks you! i'll give it a try!
