Migrate WINS from Server 2008 R2 to Server 2012

Hello Experts,

   I have been tasked with migrating roles from a Server 2008 R2 DC to a Server 2012 DC. This client still uses WINS as they have some legacy equipment requiring WINS. I have no experience with WINS and have not been able to find documentation on migrating WINS from 2008 to 2012. I did find this article:

http://ashifuzzaman.blogspot.com/2010/09/dhcp-and-wins-server-migration.html

which shows a migration from 2003 to 2008, but I wanted to check if it is valid for 2008 to 2012. I was also curious if there is a better way to go about this, as this will require us to take the database offline. I would like to set up replication if possible, and point the devices to the new server while the old server is still running, so we can fail back if needed.

I have added the WINS feature to the 2012 server and I see there is an area to add a replication partner, but I do not want to break any current database, I want to be sure I configure this correctly.

I have no problem migrating DHCP scopes, and DNS will replicate automatically since it is AD integrated, I am just skeptical about the WINS role. I'm not sure if it has any dependencies. I'm also curious if I migrate the DHCP scope to new server and demote the 2008 server, if WINS will still function, or if it relies on any DNS features. Thanks in advance!
