With regular WordPress, when you install it on your server you are given the option to change the table prefix to something other than “wp_”; however, in WordPress MU there is no option for this. So here is how you can do it from a CLEAN install.

In your wp-config-sample.php file find the following line

$table_prefix  = 'wp_';

Then change ‘wp_’ to anything you want preferably with an underscore at the end; something like the following would work.

$table_prefix  = 'muxyz_';

This will as mentioned previously only work on a Clean install so if you want to do this on a version of MU that is already running this won’t work unless you alter all your tables in your database as well.  Regular WordPress has plugins for this but I do not know if the they will work on MU and have yet to find one specifically for MU.
