Help for Redirect

Hello everyone, I ask you to help a Redirect please

I have a linux server, and I'm transferring a site made with Vbadvanced, vBulletin, vBSeo and Wordpress

I almost finished moving all the data, I would like to know what Redirect I must set nell'Htaccess then, my structure looks like this:

• blog.mysite.it (wordpress)
• mysite.it/home (vbadvanced)
• mysite.it/forum (vbulletin)
• emule.mysite.it (wordpress)

I want someone who finds an article on the Google Blog, will be transferred at the same news on blog .. but on new domain.
Same thing for eMule, Forum, etc. ..

Can you help me, please?

Thanks..

So, I begin the transfer, now I am using this htaccess from old domain:

Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*) http://www.mydomain.it/$1 [L,R=301]

Redirect is quite perfect, I checked from Google and it redirect url well, I have only problems with this url indexed:

www.p2psin.net/Applicazioni-Online/
www.p2psin.net/Table/Attualita/
www.p2psin.net/Table/Downloads/
etc...

This url are made when I used Joomla Portal, now on new domain I use vBdavanced, and it are not redirect on my server.

I want redirect only this types of url to www.mydomain.it

What code must I add in htaccess?

Thanks
