ESXi 5.0 U1 & U2 servers with vCenter Server 5.0 U1

hi all,

I have a question about  vcenter server.

Can I add servers ESXi5.0 U1 and ESXi5.0U2 to "one" vCenter 5.0 U1 ?

and
Can I add them in the same VMHA Cluster Group

and Is it run normally ?

if it is not supported, pls let me know.

Thanks
