Transferring FSMO Roles New Domain Controlers


At the moment I have 2 X 2008 DC at the moment, both non R2 standard vmware machines.
One of these DC currently holds all 5 roles.

I am planning to burn one of the current DC the one holding all 5 roles actually.
Planning on bringing in two new 2008R2 DC.

I have to put a plan together to remove the current main DC and bring a new DC in place of it and upgrade our forest and domain levels to 2008R2.
The reason I am posting here is in regards to the overall setup and particularly the infrastructure role.
I read that if your AD forest supports forest trusts the infrastructure role should be hosted on a non global catalog domain controller.
We do not currently support any trusts but we will have one established soon for a cross forest migration.

My plan is to bring on two domain controllers, both standard 2008R2.
make them both domain controllers, one of which will not be a global catalog server.
transfer all roles(barring the infrastructure role) to the new DC that is a GC.
transfer the infrastructure role to the new non global catalog domain controller.
update the forest and domain functional levels.

how does this sound?

Make them all GCs that is the recommended best practice today.  More on that here

Also if the recycle bin is enabled the IM role is no longer relevant (still a role but it doesn't do anything)
