WordPress MU

I want to move wordpress single user to wordpress multiuser.
What I have did is,
1. Install wordpress MU.
2. Create a new wordpress MU blog.
3. Export single wordpress blog using wordress Tools in dashboard.
4. Import that XML file into wordpress MU.

But through this way I don't get plugins/themes like my single user wordpress.

Way 2: what I tried.
1. Install wordpress MU.
2. Create a new wordpress MU blog.
3. Login to wordpress single user database and export mysql database into a sql file.
4. Change all table name into wp_id_ format.
5. Created those tables.
In this way I dont get any post and even plugin/themes.

Please help me , Am I missing anything.

Note that two domains are different.

See this thread re moving WP site to WPMU.

Already looked them. No help.

From those two links that you posted in that post,
first one is wrong information.
second link does not work.

If you want your plugins and themes from the single WP install in WPMU you need to copy them over and put them in the appropriate directories. They are not moved as part of the blog export process

Be warned - some WP themes aren't WPMU compatible.

I copied into /wpmu/wp-content/blogs.dir/2/files/ but it did not help any.

I used wordpress admin panel export of wordpress SU and then import into wordpress MU , only I can see the post in wordpress MU but to get plugins and themes what to do please.

And also I installed wordpress in example.com/mu but I want to see my site in example.com . What to do for that?
Thanks.

You install per blog plugins in exactly the same way as you do with WP - put them in the plugins directory and enable them from the admin backend.

Themes you put in the themese folder and then go into the theme admin screen for the site and enable each theme you want users to be able to use.

If you installed it in a subdirectory and didn't mean to then why not remove everything and install it at the top level and start again.

Is there any simple way to implement the theme of wordpress to wordpres MU by copying the files?
THank you.

What do you mean?

I stated that you copy the theme files over into the theme folder and and you need to activate them before people can use them
