Help Me Move To new domain

Hello
Can someone tell me the steps of moving my forum from one domain to another, both resides on same (dedicated)server. I just dont wanna loose my place from Google. Also, If anyuser visited my old link he/she should be redirected to new domain seamlessly.
For example:

Code:

   Old: www.forum.com
   New: www.forum.net

So if a user type "www.forum.com/thread-title" he/she should land at "www.forum.net/thread-title"

Also, is it okay to use same Database? Or should I create new username under new domain account?

Thanks

I would suggest not doing this. .com is better than .net, and you won't have to move and go through a re-indexing period to be there.

They reason why I am doing this is because my .com domain is blocked by adsense.. So, I thought if I removed all the affected content and move to new domain would allow me back to have adsense...

in this case, what do you suggest?

I would remove the content and send an appeal into adsense. Domains are never permanately blocked.

I did that also, but no luck. So I can only think of changing Domain name so generate some revenue(of course I will re clean all the messed up content)

And if you think .net is no good how about change domain.com to do-main.com or something like that?

It is entirely up to you which domain you want to chose.
