Before initiating an upgrade to vCenter 6.0 U2, I just want to see what procedures did you employ to successfully update your vCenter server and external PSC?
The order of components update and a good backup strategy are the best practices that you should follow. The following KB article shows the update sequence (including other VMware components): Update sequence for vSphere 6.0 and its compatible VMware products (2109760) | VMware KB
Thanks.
