migrating DFS from Win2k3 DCs to Win2k12R2 DCs

Hi,

I have been hosting a DFS mapping on Windows 2003 servers these past years. The DFS mapping is only used to combine several shares on site file servers into one share /  mapping.

So S: what the user sees is \\domain.company.tld\TopShare

and TopShare has several directories called <sitename> each linked to \\SiteServer.domain.company.tld\FileShare

No replication is involved.

I now want to move everything to our new 2012R2 DCs. Can I simply add DFS to those DCs, add them to the existing DFS structure and remove the old 2k3 DCs?

Or do I need to do something extra, because the whole DFS structure has changed a few times after Win2k3 ?
In that case, WHAT do I need to do extra? There is probably a good KB article about this but just searching for DFS etc gives WAY to much hits. :-(
