Steps for Moving Multiple WordPress Installs to a Multisite Install?

Question

(Moderator's Note: Original title was: "Steps to move multiple wordpress installations to a WP MU installation")

Any tips on moving multiple WordPress installations to a single Multisite[1] installation?

[1] Multisite is the new name for WPMU.

Answer 1

For the record MU functionality was merged into core and is now referred to as multisite.

Answer 2

It's not really all that hard.

1. setup the new blog on the MU install
2. import the content from the old blog
3. check content and permalinks to make sure it's all there
4. map the domain
5. have a beer

I've done it a number of times and never really had issues.

Answer 3

A couple extra handy links if you want everything in the db and have loads of images (there's some gotchas).

• Importing a single WP blog to a WPMu Installation
• Migrating single WordPress installations into multisite networks

Otherwise, it's just like Curtis says. Export / Import.
