Migrating data from one server to another

Here is the situation:
Client has two Windows Server 2003 boxes that are used as NAS using DFS
Client has tasked me with migrating all SRV2K3 boxes to SRV2K8R2

I was going to copy the DFS drive data to a dummy large storage unit (which uses FreeNAS), wipe the phyiscal server, install Windows Server 2008 R2 Enterprise Edition and configure the File Services Role. I can then setup the DFS roots etc and copy the data back over.

What I want to be sure of is the security that is in place now is intact.

Whats the best way to go about making sure the security stays in place?

Thanks

Thanks. Will the permissisons stay in place if copying from Windows to Unix based Nas?

What I may have to do is do a P2V of the unit to the clients VMWare system, then rebuild the server then do a RoboCopy with the /MIR switch.

Thanks

Thats depends of your partition... ex2/ex3 has own permissions schema different from Windows. You can try connect this share as NFS, secure to access only from Windows Server host and create folders with those permissions.
