Hi Team,

Can i upgrade ESXi4.1 to ESXi5.1 Update 3 which is running under vCenter 5.1 update 1 B ??

We have a plan to  upgrade ESXi4.1 to ESXi5.1 Update 3  (build 2323236) which is running under vCenter 5.1 update 1 B  (Build 1235232) ??

Should i need to upgrade vCenter  to  latest version in vCenter 5.1 or .. I can directly upgrade my ESXi servers to 5.1 Update 3 ?

Thanks in advance,

You can check for supported configurations at VMware Product Interoperability Matrix. According to this InterOp matrix, you can run any ESXi 5.1 version/buil on any vCenter Server 5.1 version/build. So unless the ESXi hosts have previously been upgraded from a 3.x version, and the hardware is supported for ESXi 5.1 the upgrade should work flawlessly.
