Split one mdf file into several files

Hi, 

I have a huge (over 1 TB) SQL 2008 R2 database that has one .mdf file. I need to migrate the database to a another server but the new server only has several smaller drives, so I need to split that one .mdf file into several files. I have searched the forums and it seems that one way is to have multiple filegroups and move tables into them. I am not sure how to do that, or if there is another way. Your advice please?

Thanks.
