Moving config from fim 2010 to fim 2010 R2

I am taking a old, stressed install of FIM and planning to move it to a FIM 2010 R2 environment where the Database Role and the service and portal are built on R2 and are separated as per best practices.

Can I:

Import FIM 2010 MA's , schema and config into the new FIM 2010 R2 environment.

Or

Do I build the new environment to the same spec as the old one, then do the config changeover, then upgrade to R2.

After do the discovery imports on the setup and verify sync.

Is there an easy way to do this :)

I mean, I am unsure the current environment will survive or have enough resources to take the R2 upgrade. I would prefer to build the new setup and get the rules from the old server over.

Thoughts would be greatly appreciated.
