upgrade process wp mu 2.9 to wp 3

Component: Upgrade/Install Keywords: upgrade mu

i have experimented with some upgrade scenarios and i hope you will be able to look at what happens in the backend or document the process.

the first step was starting from a clean wp mu install. this worked perfectly from 2.9 to 3.0 beta 1 by overwriting the entire content of the previous mu install. a warning came up about the salt of nonce key and the removal of the deprecated blogs.php from wp-content. then upgraded the network blogs was also fine.

up to here all was perfect, excellent work!

then i decided to upgrad to the nightly build using the beta-tester plugin and things became problematic.

the install gave me errors in the database structure; when i tried to use the 'repair' option, i've lost completely the MU features and the access to the superadmin. tables were also corrupted making it impossible to go back.

basically the upgrade, somehow turned the installed version into a single user build. not good! trying to go back to 3.0 beta 1 also didn't work (the single user was working fine at this point), and obviously the old mu version could not recover because tables were changed by the upgrade.

We've done a lot of changes to the MU upgrade process recently. Additionally, the development version of the beta tester plugin now supports MU -> 3.0.
