vCenter in another Site

Hi,

  I am looking to move my vCenter Server to our Branch Office instead of the Main office. We are looking to use the Branch Office for BC/DR solution and everything I research basically requires a vCenter in the DR site. I know I will not lose any functionality with the Cluster in the Main Office but what sort of issues should I be concerned with or looking for with having the vCenter Server in the Branch office? Below is out setup

Main Office:

1 Data center

2 Host in

1 Cluster with about 30 VMs

Branch Office:

1 Data Center

1 Host about 10 VMs

Using Site to Site ipsec VPN each site with 10 Mbs or better connection.
