Can ESXi 5.1 VM runs on ESXi 5 Hosts ?

Hi,

We have updated one of the ESXi Hosts to Release 5.1.  VMs running on that Host are updated with the latest VMWare Tools as well.

However, we have to migrate one VM to a cluster of ESXi 5 Host.  We just wonder whether there will be any compatibility problem for runninng a VM with latest VMWare Tools (i.e. the one from ESXi 5.1) with ESXi 5 Hosts ?

Thanks
