Demoting 2003 DC, DNS, WINS, DHCP and File Server

I have a legacy 2003 server that is configured as a DC, DNS, WINS and DHCP server, as well as a file server.  

I have stood up 2008 domain controllers with AD-integrated DNS and DHCP services locally, and WINS will be provided centrally.  I should be able to remove WINS and DHCP services from this server as a result.

Here's the big question.  I want to demote the legacy 2003 domain controller and leave it running as a file server.  Has anyone heard of issues like NTFS permissions getting scrambled as a result?  Any issues at all?

Can I complete the DC demotion cleanly while retaining the file server role?

Thanks for your help!

Make sure you have checked below things
1) Roles transferred to new DC
2) New dc is global catalogue
3) replication is perfect between both the DC's
4) Clients are pointing to new DNS server in there NIC card
5) New DHCP server is authorised in Domain
6) Health of new dc using dcdiag /q and health of new DNS using dcdiag /test:dns

Refer below too if I missed something

NTFS permissions will not be affected. Just make sure you that you change DNS settings to point to the other DNS servers if you are removing the DNS role.

Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

AD roles will automatically be transferred to other DC's if they haven't already when you brought up the newer DC. As a precaution you can transfer them manually if you would like but DC demotion wont even complete if role transfer is not successful.
