DFS or Hyper V replica which one is better

Dear All,

We have 2 file server running on windows server 2008 one in primary site and the other in DR site currently DFS and robo copy is being used to replicate the date between both the sites.

We are planning to migrate the windows server 2008 to windows server 2012 R2 and run the server in virtual environment with Hyper V, based on this i have couple of questions

1) i heard of hyper V replica through which i can replicate the entire VM to other site,by doing this can i stop using DFS and robo copy is this the best alternative to DFS and robo copy.

2) in case if the primary site is down can i start the VM in DR and just change the IP on DNS server and user can start accessing file server from DR server?

3) is there any option available in hyper V replica to monitor the replication?

Regards
