migrate roaming profiles to user profile disks

Hello,

I am in the process of building a new RDS deployment with the following servers:

FS1 - File server which is the repository for the User Profiles
DC2 - RD Licensing server
CB1 - RD Connection Broker
RDGY1 - RD webaccess 
SH1 - RD Session host
SH2 - RD Session host

We have all the users profiles mapped from the location FS1\users. I'm currently evaluating the possibilities to use "user profile disks" using the same profile path. How to achieve this ?
