General SYSVOL migration from FRS to DFSR

Question

Hi all.
I have a question regarding Sysvol Migration from FRS to DFSR.
We have migrated all of our Domain Controllers from Server 2003 to Server 2008 R2 about 2 years ago.
I know that if Server 2003 was in use initially and you upgrade to Server 2008 R2, you need to do a FRS to DFSR migration in order for you Sysvol to make use of DFSR.
My question is if we are upgrading now to server 2012 R2 would there be a time that this would happen automatically or do we still need to do the sysvol migration before upgrading to server 2012 R2.
Another question I have is do we need to do the FRS to DFSR migation on all our child domains as well ?
Many thanks for your time.
Your answers would be appreciated.
Kind Regards,
Shaun

Hi There.
Yes that would be great. I would probably use the active directory removal method but I dont know if this would work as its the last domain contoller and it is not replicating with the top level domain at the moment.
NTDSUTIL would probably need to be used ro list the servers in that domain and remove them and then if I'm correct I would need to remove the domain namig contect with the instructions below.
Removing Orphaned Domains from Active Directory
Determine the domain controller that holds the Domain Naming Master Flexible Single Master Operations (FSMO) role. To identify the server holding this role:
Start the Active Directory Domains and Trusts Microsoft Management Console (MMC) snap-in from the
Administrative Tools menu.
Right-click the root node in the left pane titled
Active Directory Domains and Trusts, and then click Operations Master.
The domain controller that currently holds this role is identified in the Current Operations Master frame.NOTE: If this changed recently, not all computer may have received this change yet due to replication.
For more information about FSMO roles, click the following article number to view the article in the Microsoft Knowledge Base:
197132 Windows 2000 Active Directory FSMO Roles
Verify that all servers for the domain have been demoted.
Click Start, point to Programs, point to
Accessories, and then click Command Prompt.
At the command prompt, type: ntdsutil.
Type: metadata cleanup, and then press ENTER.
Type: connections, and then press ENTER. This menu is used to connect to the specific server on which the changes will occur. If the currently logged-on user is not a member of the Enterprise Admins group, alternate credentials can be supplied
by specifying the credentials to use before making the connection. To do so, type:
set creds domainname username password , and then press ENTER. For a null password, type:
null for the password parameter.
Type: connect to server <var>servername</var> (where <var>servername</var> is the name of the domain controller holding the Domain Naming Master FSMO Role), and then press ENTER. You should receive confirmation that the connection is successfully
established. If an error occurs, verify that the domain controller being used in the connection is available and that the credentials you supplied have administrative permissions on the server.
Type: quit, and then press ENTER. The Metadata Cleanup menu is displayed.
Type: select operation target, and then press ENTER.
Type: list domains, and then press ENTER. A list of domains in the forest is displayed, each with an associated number.
Type: select domain <var>number</var>, and then press ENTER, where <var>number</var> is the number associated with the domain to be removed.
Type: quit, and then press ENTER. The Metadata Cleanup menu is displayed.
Type: remove selected domain, and then press ENTER. You should receive confirmation that the removal was successful. If an error occurs, please refer to the Microsoft Knowledge Base for articles on specific error messages.
Type: quit at each menu to quit the NTDSUTIL tool. You should receive confirmation that the connection disconnected successfully.
Thanks again for all your help.
Regards.
