Thank you. the reason I hesitated to upgrade vCenter is because I was not sure of its compatibility.
According to HP, the highest update I can go in respect to HP server Proliant Gen8 is 6.5 U2 pre-gen9.
However, latest hypervisor and vCenter versions are 6.7 U2.
Is there a problem running vCenter appliance and hypervison 6.7U2 on 6.5U2 ESXI?
If not, in what sequence should upgrade be made? vCenter first then hyperviso or oppositer?
