SRM 5.1 fails when recovering a VM to a host with less virtual CPU than at the Recovery Site

Hello:

We are trying to run a Recovery Plan from our Protected site to our recovery site.  During a 'test' recovery, one of our Virtual machines with 12 CPU allocation at the Protected site, fails with the following error:

Error - Virtual machine has 12 virtual CPUs, but the host only supports 8. The number of virtual CPUs may be limited by the guest OS selected for the virtual machine or by the licensing for the host. Virtual machine has 12 virtual CPUs, but the host only supports 8. The number of virtual CPUs may be limited by the guest OS selected for the virtual machine or by the licensing for the host. 

Basically, the VM (at the HOST site) has been allocated 12 vCPU, but at the Recovery Site the max we can allocate is 8CPU. 

When we run a recovery plan on that server, the server fails to boot with the error above.

We do not really want to spend money to increase the processors at the recovery site.  Is there a way to setup SRM to define the number of vCPU that the machine should spin up with at the Recovery site? 

How would this be accomplished?  Any guidance would be appreciated.

Thanks

Create a Pre-Power On script to reduce the vCPU to something suitable.
