vCenterServer 6.0U3b with ESXI Hosts 6.0.0 4600944 (Dell customized) ?

Hello,

I have a system with three ESXi Hosts and one vCenter Server all running on ESXi 5.1.0 (1483097).

I don't want to upgrade the vCenter Server (on W2012R2), but install a new one. The ESXI host will be upgraded to  6.0.0 4600944 (Dell customized).

When I do a new installation of the vCenterServer on W2012R2 which version shall i use? Can I use the newest version vCenterServer 6.0U3b or shall I use VMware vCenter Server 6.0 U2 for the ESXi host running on 6.0.0 U2 ?

Thanks a lot,

Michael
