vMotion scenario

Hi,

I have 1 master VM with 1 slave VM, so when Master vm  goes down, it is automatically vMotion into slave VM. Now I want to add another Master VM and run it as DB server and when it goes down I want it to be migrated to the same slave VM as existing master VM. Can this be done?

Scenario:

1 master vm & 1 slave vm is in pair already.

Add 1 more master vm to be covered by the same slave vm.

Thanks,
