ESXi 5.5 upgrade to 6.0 or 6.5?

I'm upgrading my 3 ESXi hosts from 5.5 this summer and I was planning to go to 6.5 but I was on with support last week with a disk consolidation issue and the engineer told me I should not go to 6.5. He recommended 6.0 update 3. Anyone else agree with this?

I am already running the Vcenter 6.5 appliance and plan to us update manager.

Thanks in advance

Did the engineer tell you the reason why he recommended v6.0?

The only reason against v6.5 that I can think of, would be a hardware incompatibility.

If your host support ESXi 6.5, I'd say go for it.

I agree with André.

As long as the hardware is compatible there is no reason why you should not update to 6.5

You could check for yourself if your hardware is compatible using the VMware Matrix:

VMware Compatibility Guide - System Search

Also check if any upgrade path incompatibility exists:

Cheers!

As mentioned already there is nothing bad with 6.5. I believe the engineer mentioned this because of your hardware, maybe some of your components might not have custom drivers. This was my case and had to stay on 6.0 till I upgrade my hardware. What I can say is ask the support engineer one more time to really specify why he mentioned that you can't do the upgrade.

6.5 is absolutely OK to use in production environment but as others aleredy said do not forget to check your hardware aggainst HCL
