Vmware VCenter 4.1 update 1 and adding an host ESXi 4.1 update 3

Hello -

I am currently running Vcenter 4.1 update 1 with 1 cluster running 6 ESXi 4.1 update 1 Host.  I was wondering if I am able to add another host to this cluster with ESXi 4.1 update 3. The reason for this is my hardware is only compatible with this version and need to add more resource to this cluster.
