Hi,
Currently SRM can not work within a single vCenter Server instance topology.
However, vSphere Replication 5.1 (requires vCenter Server 5.1) can. You can use the VR UI plugin, accessible through the vSphere Web Client to configure replications for the virtual machines and perform recovery at the new hosts. In the VR UI there is no orchestration or IP-customization support, like in SRM, but you should be able to configure replication and later perform the migration via the recovery wizard with minimal downtime. Currently the VR recovery wizard is for a single VM, so you will need to go through it for each VM. The actual recovery tasks can execute in parallel.
Regards,
Martin
