The files is only part of it - you will need the database as well. You can download the files, but without the database, all you'll have are errors. Your templates and styles are located in the database, so regardless if you want your users/threads/posts - you won't be able to use one without the other. The only other option is to do a fresh install and install everything again manually (in that case you'll just need your files) - but you won't have all the updates and changes you've made - you'll have to re-do them.

Also, keep in mind, with changing hosts, you'll also change paths too. Your /old/path/to/your/forums will not be the same as your /new/path/to/your/forums
