Upgrade 6.0 VCSA w/external PSCs to 6.7

[BHagenSPI]

What pitfalls will I encounter by upgrading my 6.0 VCSA w/external PSCs environment to 6.7?

Can I leave my 6.0U3 esxi hosts at 6.0U3, or do I have to upgrade them to 6.7?

I currently have 7 hosts (esxi 6.0U3), a VCSA (Build number 4823866), and 2 external PSCs (Build number 4823866). The vShpere Web Client is Version 6.0.0 Build 6855238.

I am building 6 new hosts with esxi 6.7, and plan to migrate all our VMs from the 6.0U3 stack to the 6.7 stack. (Then I'll wipe the 6.0U3 stack clean, rebuild all the disk groups (since I messed them up when I first built it and have had capacity and congestion issues ever since), update those hosts to esxi 6.7, and use that stack for DR.)

I *think* my best course of action is to update my current VCSA environment to 6.7 and add the new hosts to the cluster; that way I can simply vmotion the VMs to the shiny new hosts, rather than mess with replicating and failing over.

Is this reasonable? What pitfalls will I encounter?

Thanks!

They explain the nuances pretty simply.

Hi,

Update the PSCs first, followed by vCenter. vCenter 6.7 can manage ESXi 6.0U3.

After that you can add the new ESXi 6.7 hosts and vMotion the VMs from the older 6.0 U3 hosts.

Hadn't seen that KB; very nice. Interesting that vsan is the very last link in the chain to be upgraded.

Thanks!
