ESXi upgrade from 4.1 to 5.1

Can I upgrade my ESXi 4.1 hosts directly to ESXi 5.1 Update 2, or do I need to go to ESXi Update 1 first?

Your comments are appreciated.

Thanks

You should be able to go straight from ESXI 4.1 to 5.1 Update 2.

However, you should check to make sure that the hosts are on the HCL for 5.1 and backup any configurations before upgrading.
