Recover virtual machine when vcenter is down too

Hello everyone,

I´m new to VMware vSphere replication, and i have a question about replication with only once vCenter. I have :

1 site A with 1 ESXi 5.1 with vSphere replication 5.1 (web console and 1 appliance)

1 site B  with 1 ESXi 5.1 to hold the replication.

Ok, the replication is fine between these sites, but if i LOST my vCenter, is there a way to recover it in site B, since i need vCenter to click "Recover".

Or should i put the vCenter and the appliance in my Site B (not production) and replicate Site A Virtual machines to Site B?

thank you for any information.
